They had to brief me on all of the possible dangers in the lab building (which were many) as that was their policy for contractors. The entire complex was designed for testing and had blow out walls, containment rooms, special air handling systems, etc. They said they once had an accidental release of the gas and the cloud floated across the parking lot and etched the car glass as it floated by. They had sealed containment rooms for running tests with that stuff. They used the acid as a feed chemical to produce teflon based products. The guys I was working with advised me to avoid walking in that area of the building since any exposure to the chemical would likely mean death. It is a really nasty chemical. http://en.wikipedia.org/wiki/Hydrofluoric_acid Dave --- This email is free from viruses and malware because avast!

Silicone oil, most easily available as DOT-5 silicone brake fluid, is an excellent life prolonging lube for sleeve bearing fans. But it must be applied before the fan gets noisy. The brake fluid has next to zero volatile components so it will never dry out and its heat tolerance is far higher than whatever lube is used on the fans so it's ideal for use on fans mounted to hot CPU coolers. One pint of the stuff is a multi-lifetime supply. Silicone oil is also used as a dilutant for RTV silicone to thin it and as fuser oil in some laser printers and copiers. Don't often see ones with a tank of the oil anymore. Most get by with whatever amount is soaked into a high temp felt pad.

Jon That could be used IF the endpoint was a bad match, but in terms of a TDR, if its a 6 bay superturnstile antenna that is actually well matched at its normal operating frequency, is such a mess on the TDR screen as to render it worthless. If you know the exact footage to the splitter at the center of the antenna, then one could use that bump as a known distance, then ratio the thing to where the fault is. So basically, that cat is going to be skinned regardless. Unforch, the normal fault fail when there is 20+ kilowatts of synch tip power available to really burn things up, it winds up being a short, or an open, so nothing beyond the problem will be seen on the screen anyway. Once the fire is started, unless the transmitter sees the fault and shuts itself off, it isn't unusual for the fire, which crawls toward the power src at a fairly high rate of speed, to burn up stuff from the original failure point all the way back to the 4KM100LA's output cavity, and its the arc detector watching the cavity that actually initiates the take down sequence. But at that point you may be pulling 1000 feet of 6.125 75 ohm line down, cleaning and replacing burnt teflon as you go. Usually thats a 3 to 5 day job depending on how far away the teflon stuff is and whether the local lumber yard/paint store has enough alcohol to get it cleaned up.

But if the supplier were to go west, I'd still remain on air for as long as the source code for a compatible linux version can compile on a piece of hardware I can buy. My suspicion is that I'll wear out before that happens. For just a logic analyser, an open source product, like the one mentioned upthread, provides complete vendor independence.

And it ought to be possible to run the old OS on the old hardware until it succumbs to entropy. Buying one or two old hardware mobos, recently manufactured, should then add up to another decade, with a bit of luck. However, it's not as future proof as having the source code to the OS, and being able to do a backport yourself (or pay someone to), if necessary. With an ethernet connection, and a linux hosted app, the one I use is really only reliant on linux system calls, X11, and TCP/IP, I figure. Oh, and a DLL, I remember. In contrast to relying on both M$ and the gadget vendor continuing support, the exposure is halved when only the latter needs to continue, because linux distros abound, and loss of any one has no great effect.

The sheer volume of photographs makes organizing them tedious and therefore unlikely. When you die will your kids methodically go through them all and re-organize into their photo albums? Or will the CDs, and the plastic jewel cases be tossed into recycling. And on top of that, the printed photos will themselves have faded or spontaneously combusted/composted due to some weird chemical action over time. Even the archival quality inks (and who uses them for family snaps?) only have a /simulated/ lifetime that hasn't been put to the test yet - its just hopeful extrapolation from accelerated heat UV exposure testing. I had occasion to re-burn some old discs a while ago, several were from the era of single speed CDRs, and I foolishly put them in a drive that can read at 52x. Second disc in literally exploded. Very loudly. I thought it was the PSU caps so leapt up and yanked the power lead. When I dismantled the drive it was full of metallic confetti and SMALL shards of polycarbonate, none bigger than a thumbnail. It totally banjaxed the drive, I was quite surprised at the amount of energy in a small spinning disc. The fragments left deep gouges in the CD tray. Luckily I had a later backup which I made sure to read at 2x. Now I mainly use a stack of obsolete HDDs and copy from one to the other every few years. I use a fair few 35GB Rev discs too, and give sets to family to stash.

But in troubleshooting existing cables, I have yet to see anything work slicker than a good TDR. You can have a bullet burnout someplace in a 2100 foot run of high powered coax, take a look at it on the TDR and tell the tower crew within 5 feet of where to take it apart. The 5' error? Probably the operator, not knowing the exact propagation velocity of that particular line using a SWAG instead. From there of course, they may have to take several sections below it to clean up the burnt teflon soot, but it saves them time you money for the high steel people on site if they don't have to take the last 140 feet of it apart looking for the problem. I've even used a homemade one, using F family chips for pulse drivers and a 100+ Mhz scope some math. It worked well enough to hit the bad joint. And some local frogs who had never seen a TDR were telling me I was wasting my time. I told the crew to take the tower top jumper on the west side apart and if it was clean, start down, the line was slower than my data said it was. The jumper was 4 elbows arranged to form a U shape with the U laying horizontal. The vertical lines go up the face of the tower, and this jumper went from the vertical line to the line going up the antenna mast itself, a run of about 32 if the tower is Stainless G5. The line springs had gradually pulled the line up, slightly over stretched, and the U had about a gallon of water in it because the line had been pulled up about 4, creating a low spot for moisture to collect. Its a pressurized line, 2 to 3 psi of dry nitrogen in it, operator checked replenished if needed 2x daily, so the ONLY way that water got in was the last crew put it together wet. And they knew it because they had to wait for the rain to stop before work resumed the next day, after leaving it open when they quit the night before, not even a garbage bag tied over it. The tower crew that originally did that work for me has never been on site again, per my orders. We were probably out some north of $50,000 in lost air time, make goods and extra work because they were so sloppy. -Original Message- From: Lester Caine [mailto:les...@lsces.co.uk] Sent: October-09-14 3:28 AM To: emc-users@lists.sourceforge.net Subject: Re: [Emc-users] Oscilloscope + logic analyzer (PC based) On 08/10/14 23:05, John Dammeyer wrote: Sorry. 3GHz.

Second disc in literally exploded. Very loudly. I still have the very first CD-R I ever burned. Used a 1x or 2x speed SCSI Sony burner and the disc used the dark green dye. It was even readable in an old 1x Mitsumi drive, the one where the whole mechanism slides out with the clamshell lid. Crazy thing is that original 1x Mitsumi drive was not supposed to be able to read any CD-R, no matter what. Still readable even after 17 years. The nearly invisible blue dye is nowhere near as reliable as the original dark green or dark blue dyes. It does have one error in one Windows 95 CAB file. Dunno what the problem was with that one file but whenever I'd build a PC I'd always have to burn two copies of Windows to the disc to go with the system because every time that same CAB file would develop an error in one copy, though both were read from the same source files. The extra crazy thing is both copies would verify 100% against the source then the one file would suddenly develop a read error - and it wasn't just with one burner. I've only had one CD-R go to pieces on me. It had a crack at the hub which extended just into the TOC zone. I tried using Unstoppable Copier to recover the data. It wasn't having any luck, the drive would spin up and down over and over then suddenly it revved up to max speed and BANG! Plastic confetti. I was looking at it so I saw the front of the tray pop out. Shut it down, took the drive out and apart. Shook out the debris, popped the front back on the tray and no problems with the drive. Something quite annoying about recordable optical discs is stores either will not stock dual layer DVDs or if they do they only have extremely overpriced 3 or 5 packs in jewel cases or at most 25 disc cake boxes. Staples only stocks 25 disc cake boxes of Maxell DVD+R DL - the absolute worst brand of DL media made. Out of six or more burners I have only ONE will work with them. HP 2.5x speed DL media was also rather horrid. Drive compatibility was decent but I had almost a 50% write failure rate. When it comes to rewriteable DVDs, most drives support up to 8x RW discs but just try and find any DVD-RW faster than 4x. And where are the Blu-Ray drives, burners and media? I've never seen any BR drives of any kind at Staples and for only a short time did they have any discs. Dual layer DVD, 8x DVD-RW and BD-R/RE are all turning out to be like the 2.88M floppy disc. Stores that sell computer supplies and parts should have had shelves full of all these for the past decade but have either failed to stock any at all or only made tiny token efforts at selling them. The old We don't have that because it doesn't sell well. BS! You can't sell what you refuse to put on the shelf! If Wal-Mart would order a billion *good quality* dual layer DVD blanks and make sure all their stores had 50 and 100 disc spindles of them, the media would sell very well - and Staples, Office Max and the rest would have to stock them too. --- This email is free from viruses and malware because avast!

My big Tek analyzer has 128K per channel, 96 channels per board, and I think that is actually two bits/sample for the glitch memory. It takes maybe six seconds to format up the region you are viewing, and every couple pages you scroll in time, it takes another six seconds to do it over for the new region. Kind of a pain to find what you are looking for. On the other hand, it can capture several servo periods at something like 20 ns per sample.

Re: [Emc-users] Oscilloscope + logic analyzer (PC based)
I own an EPROM/PAL programmer that runs off the parallel port. At the time to get the PAL feature I paid a significant amount for it. The shift from Windows 3.11 to Win95 orphaned the product two months after I bought it. I kept a WIN3.11 system around for a few years but doesn't matter anymore because I don't use EPROMs nor those PALs. I also own a 32 channel logic analyzer pod that runs off the parallel port. Last time I was using it was WIN-98 or maybe XP. I wrote custom DLL code for it to do CAN bus decoding from the bit stream back in 2001. I haven't tried it with WIN-7. Don't know if it will work. None of these products were supported under Linux. Doesn't matter as much as I now have a stand alone 4 channel Tek Scope with a 16 channel logic analyzer that also does SPI/IIC/CAN bus decoding. Although companies are full of the wildest dreams of staying in business forever (or in the case of AlibreCAM being purchased generating a ROI) the truth is supporting old hardware is really expensive. We live in a throw away world and that logic analyzer/scope that works today on WIN-7 may not work on WIN-9. And when your WIN-7 hardware fails the license for that scope module which was keyed to the CPU no longer works and the company that sold the scope no longer supplies upgrades for WIN 9.00100. The problem is test equipment sometimes sits there for months not being needed. It's like the bandsaw in the shop. If you don't build anything for a few months that requires that tool it sits idle in the corner with a dusting of sawdust on it. But when you need it you walk over to it and turn it on and it works. I do that with my Delta Saw built in 1935. I can also do that with my 30MHz Gould Scope that I bought in 1978 although I suspect I'd probably have to replace some filter capacitors. Not a problem since the user manual came with Service Information and Schematics. Just an observation that these little pocket scopes and logic analyzers have a very short lifetime.

Re: [Emc-users] Oscilloscope + logic analyzer (PC based)
It gets more complicated, though. We have a lab full of Tek logic analyzers (about 10yo if I recall). They had a retail value of about $11K each I think, although we got a discount. We discovered after we bought them that they ran on Windows 2000. Last year we persuaded Tek to give us the drivers that would work on XP, and upgraded the LA's to XP. Don't know how many more times we can make that happen. I have a couple of 20yo Philips LA's that still run, but they boot off a 3.5 floppy, which is an iffy device after this many years. No idea of what OS (if any) those are based on. I discovered while getting ethernet networking going with our new Fluke 8846 bench dmm's that they are running some version of Linux. No provision for any sort of updating/upgrading on those (without significant hacking anyway). We have to be careful how we build LinuxCNC machines to avoid giving future users the same sorts of problems. I'm glad the system is headed in the direction of packages that can be added to standard distributions rather than relying on installing from LiveCD's, as I think it makes it easier to build in anti-obsolescence. -- Ralph From: John Dammeyer [jo...@autoartisans.com] Sent: Wednesday, October 08, 2014 9:06 AM To: 'Enhanced Machine Controller (EMC)' Subject: Re: [Emc-users] Oscilloscope + logic analyzer (PC based) I own an EPROM/PAL programmer that runs off the parallel port.

Re: [Emc-users] Oscilloscope + logic analyzer (PC based)
Yeah. The replacement scope for my GOULD was a TEK TDS3032 with floppy drive. Takes as much as a minute to capture the screen. Getting harder to read those floppies from Windows Systems. Not really possible to take it apart and insert a floppy emulation USB drive. So I bought a TEK MSO3034. This has USB and Ethernet. Takes forever to start up whatever OS it has. Hopefully will have at least a 15 year life. Unlike my Rhode and Schwartz Spectrum analyzer which was lucky if the battery pack lived for more than 6 months. At over $1K to replace it I stopped. And I won't buy another Rhode Schwartz.

We live in a throw away world and that logic analyzer/scope that works today on WIN-7 may not work on WIN-9. And when your WIN-7 hardware fails the license for that scope module which was keyed to the CPU no longer works and the company that sold the scope no longer supplies upgrades for WIN 9.00100. The problem is test equipment sometimes sits there for months not being needed. It's like the bandsaw in the shop. If you don't build anything for a few months that requires that tool it sits idle in the corner with a dusting of sawdust on it. But when you need it you walk over to it and turn it on and it works. I do that with my Delta Saw built in 1935. I can also do that with my 30MHz Gould Scope that I bought in 1978 although I suspect I'd probably have to replace some filter capacitors. Not a problem since the user manual came with Service Information and Schematics. Just an observation that these little pocket scopes and logic analyzers have a very short lifetime.

True. My RS FSH3 with hardware and software modules was close to $15K US 10 years ago and it's only good to 3MHz but is a useful tool. Just no longer battery operated and if unplugged loses all the setup information. It's linkage into the PC is through an optical connection to a serial port on the PC so there's no pseudo ground or weird ground connection. And the PC software has been useful.

Thanks in advance! Viesturs I think they probably work ok, but since they need a pc running windows of some sort, I have always looked at them as a solution in search of a problem. A problem I have not encountered because when all you have is a 100mhz dual trace scope, all problems are solvable with it, just like if all you have is a hammer, everything looks like a nail. :) OTOH I have little knowledge of how to properly use a logic analyzer, and that is a more complex digital field I can't comment on other than I have found hundreds of logic problems with a dual trace scope of adequate bandwidth, adequate usually being defined as at least 50x the clock rate of the circuit. In either usage here, you will have to lug around the pc too, they are not standalone devices. Generally, and unless you are designing drivers from scratch, quite meaningful information can be had from a DS201. Its not that fast, but neither are the outputs of a pc headed for the machines control drivers, stepper or servo. And if you don't wad up the probe(s) but have a suitable container for them, the scope itself will fit in your shirt pocket, but I'd use button down flaps to keep it secure when you bend over to do something else. Falling in a coolant catch tank would not be good for it. Cheers, Gene Heskett -- There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Using a laptop as host would have a secondary benefit if a battery supply were also made up for the Bitscope - total isolation! OK, that'd only rarely be of much benefit, but good for where you have to stand on a non-metal chair, wearing rubber boots, to test a bit of equipment. If you need more than 8 logic analyser channels, then ISTR that you can hook up two of them, and cross-trigger, making a 16 channel analyser. I'd send them an email if you wanted to go down that path, e.g. for the wall printer. Do you have access to the CMOS or TTL logic levels, rather than just the print head drive voltages?

Re: [Emc-users] Oscilloscope + logic analyzer (PC based)
Hi Viesturs. Be careful, the 6022BE is advertised as being a scope-only, whereas the 6022BL is a 6022BE plus the 16 channel logic analyser function - hence the price difference. (The best price on AliExpress, with free shipping for me would be US$88 for the BL and US$66 for the BE) However, if you just want to do some simple logic analyser work, then what about: http://www.aliexpress.com/item/1pcs-New-Arrival-USB-Logic-Analyzer-24M-8CH-MCU-ARM-FPGA-DSP-debug-tool/1710322113.html for US$7.80 shipping included. OF COURSE this toy cannot do what the fancy ones do, and it is only a logic analyser, not an oscilloscope, but I bought one - got good service from the supplier, and was very favourably impressed at what a cheap thing like this can do. I think you mention that you have not had an oscilloscope/ logic analyser before. You might want to go with something simple like this to get to know what it can do, and then you can be more specific as to what you want your Rolls Royce to do when you buy it. In that way you will know what you want, and pay for that only, instead of just buying the biggest and best option that you can afford. Hope that helps.

Viesturs Looking at that menu, which is quite a lengthy smörgåsbord, I think we'd need to know what it is that you want to do. Years back now, I needed a scope and all the station could then afford was a 35mhz dual trace Phillips, probably a relabel of an early J.A.Pan model. It worked well, but I could also detect its limits when using it on an NTSC video signal. Since then I haven't been happy with less that a 100 MHz dual trace. It has just enough definition that I can look at a non-ecl digital signal, and see the ringing on a level transition reach above the supply rail, or below the ground rail, far enough that I could see the substrate diodes turning on and clipping the tip of the ringing off. This is not good for the IC's and shows that the board layout needs help, but most of the time all one can do is cut the trace and insert a small (47 ohms) resistor to slow the edges a wee bit. Good for the target IC yes, but that also costs you noise margin so the net result in terms of noise margin may not be as huge a plus as you expected. Such details are quite important in TTL circuitry, less so in CMOS since the logic uncertainty is in the 40-60% of the rail voltage, but CMOS drives to within millivolts of the power rails, usually delivering a sine-squared rise fall ramp. Circuitry-wise, this is a huge improvement unless traces are many feet long and the environment is noisy enough that the trace is acting like an antenna to both radiate it, and pick it up. But recognizing that clipping is something that generally comes from 60+ years of using a scope that can show you that stuff. And that is something a logic analyzer simply isn't capable of doing until the condition actually forces a repeatable logic mistake. Thats maybe .001% of the time even in bad designs that should never have been shipped to the board house. But its often enough the gear will get a reputation as being flaky out in the field. A slower scope won't show you that regardless of the maker label on it.

Be careful, the 6022BE is advertised as being a scope-only, whereas the 6022BL is a 6022BE plus the 16 channel logic analyser function - hence the price difference. (The best price on AliExpress, with free shipping for me would be US$88 for the BL and US$66 for the BE) However, if you just want to do some simple logic analyser work, then what about: http://www.aliexpress.com/item/1pcs-New-Arrival-USB-Logic-Analyzer-24M -8CH-MCU-ARM-FPGA-DSP-debug-tool/1710322113.html for US$7.80 shipping included. Thats even cute and its not even bow legged. :) OF COURSE this toy cannot do what the fancy ones do, and it is only a logic analyser, not an oscilloscope, but I bought one - got good service from the supplier, and was very favourably impressed at what a cheap thing like this can do. I think you mention that you have not had an oscilloscope/ logic analyser before. You might want to go with something simple like this to get to know what it can do, and then you can be more specific as to what you want your Rolls Royce to do when you buy it.

Between that and a £10 USB 24Mhz logic analyser you should be set. Bit out of order to mention it I suppose, but a lot of the cheap USB L.A.s can be used with the excellent Saleae Logic software. Its got lots of protocol analysers etc builtin.

Re: [Emc-users] Oscilloscope + logic analyzer (PC based)
I have one of those devices. I'm not satisfied with it. First, the good: the java interface does work in Linux. And it is pretty cheap. The bad: almost everything else. I was particularly frustrated when I was initially trying to debug my 1.8V5V level shifter hm2_spi driver this summer. The probes I have are simple passive clip-ons with unshielded cables (.100-pitch ribbon cable). There's only one ground for each 8 channels. Consequently, it's very easy for one signal to be cross-coupled into another. Unused channels simply float unless you take care to ground them, so they either see just plain noise or a mangled version of the next-door channel. There's no control over reference voltages, so while you may be able to use it with 3.3V and 5V input signals, there's no way to set it so that it has the same response characteristics as whatever logic family you're actually using. And no go if you are working with a lower voltage than that. (it uses a MC74LCX16245 transceiver and a 3.3V nominal Vcc, so V_IH ~ 2.0V and V_IL ~ .8V) I was ultimately able to use this device to scope my SPI signals after the conversion to 5V, but only by designing my board with a header *just for* the OLS, using channels 0,2,4,6 for the four signals of interest and grounds on channels 1,3,5,7 (plus the ground to the outside of channel 0) and at low SPI clock rates like 4/8/12MHz. And the SPI signal analysis mode of the java software actually worked! It's probably a much more adequate device if you're working with consistent high drive strength 5V signals (like you'd have on the outputs of an AVR, for instance) and lower speeds can't hurt (I would have liked to scope a SPI signal with a ~40MHz clock but that just wasn't going to happen) Jeff -- Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?

It says it runs in Linux on the dangerousprototypes site. I have a Logic 8 from https://www.saleae.com/ When I got it a few years ago they were $149. It has linux software and has been a very nice and handy little tool. That OpenBench Logic sniffer looks pretty nice though - and cheap!

Re: [Emc-users] Oscilloscope + logic analyzer (PC based)
I'm pretty happy with my MSO-19 from Link Instruments. It's only got 1 channel but it does have 8 logic lines and a signal generator. When I'm in the field I'm carrying a laptop anyway, so tossing this thing into the laptop bag is a no brainer. The software is Windows, and is pretty good. They have a 2-channel version called I think the MSO-28 but it's a few dollars more.
