I had a bug in one of my windows programs that I didn't feel like fixing. It would fail somehow if I chose to over-write an existing file. So if I wanted to over-write, I would delete the old file from the open file dialog. It's also nice when cleaning up the cruft in a directory when you don't have to open the file manager to delete a few files. I generally prefer to have the freedom to use my computer the way I want, and I find the linux desktop managers to be a little clunky because they limit what you can do.

I bought one of the DSO NANO's. For what I want to use it for its adequate. Unplug the usb charging cable and its fully isolated. Cheers, Gene -- There are four boxes... How do you like the DSO Nano? I've been eyeing them for a while. About the only thing I haven't mastered is getting the sweep trigger set so I can see the actual trigger. Other than that, and a miss-match between the probe and its frequency comp that distorts a square wave somewhat, it Just Works(TM). I didn't expect it to match my Hitachi V-1065, but at 5% of the cost ... Cheers, Gene -- I have a 100 mhz HP scope for the bench, but it takes a bit to warm up (if you follow the manual's guideline). That and no one-shot event capture have me looking for another scope. Doing some very short transient pulse measurements. Good news is they are audio frequency range so no great strain on most worth-anything scopes. Looking for a good bang for the buck rig with either digital capture that can be downloaded for analysis, or even old school one-shot hold memory (and i'll take a photo of the screen). I left off looking at the Tek 2200 series with memory added when the Nanos came around. Think it might be a good fit? No clue Jason. The only tek 22xx I ever had any experience with was new in '84, a pure analog 100 mhz dual trace 2235, had a shite crt that tek would not replace in warranty, so I eventually ordered the crt ($550 at the time) and put it in myself. Generally it worked well but as usual with a tek, the input attenuators go way out of calibration and developed severe frequency response errors, really bad by '93 or so, and by then tek had done that same thing they always do 5 years after the last one rolls off the line, all the spares went to the landfill. I sent it to the transmitter site. AFAIK, it still works, but if I saw a square wave being displayed as a square wave, I'd go get my glasses fixed. My own Hitachi V-1065 works well yet today and it is pushing 30 years old. The timebase is out of calibration about 3 or 4%, but voltages are still dead on, as are the displays of a square wave. Best $1200 I ever spent for any piece of test equipment, ever. If something should destroy it, I'd buy another one just like it tomorrow. The only Hitachi scope I wouldn't touch is the V-1085, the trigger circuit doesn't.

That's true and it seemed we always needed one more cable than we could lay our hands on when my group was using GPIB aka IEEE 488 aka HP-IB extensively (into the early 1980s). Fortunately, there was always somebody down the hall to borrow one from. On the other hand, why beat on a dead horse? HP-IB was developed by HP back in the 1960s-1970s to interconnect its growing line of instrumentation products with digital interfaces. IEEE got into the act in the 1970s. The HP-IB bus was implemented in TTL. Given that, I think the usable cable lengths were pretty impressive. We took a ton of data on HP 98xx desktop computers bussed to HP instruments; processed and plotted results to HP plotters. (Anyone remember those funky magnetic program cards? I wish I had kept one for a souvenir. Indeed, I wish I had kept one of every kind of data storage medium I used in my professional lifetime.) This technology wasn't my choice---I had joined the group with extensive experience in minicompter/NIM-bin/CAMAC technologies---but taking the HP approach meant the engineers could do their own integration. At least two students won PhDs from their home universities with research based in part on the data they gathered in our group. Sic transit gloria mundi. Regards, Kent Oh! My, My. aren't memories fun. We used a HP9815 as a storage device/printer for the Atomic Absorbtion system. Tape stored the binary to reload the PDP-11 and the printer recorded the results. I suspect that was fairly good implementation for the era. :-) D IIRC HP-IB was good for 2 m between instruments. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
