Re: [time-nuts] GR 1115B
Hi It's an early Warner resonator so stress is an issue. It is drifting in the right direction. I am also worried that the tuning coil may be tough to replace. I've seen them get pretty fragile after baking for years and years. Wait and see sounds like a good plan. Thanks Bob On Jul 31, 2010, at 11:11 PM, Max Robinson m...@maxsmusicplace.com wrote: First I suggest you let it run for a couple of weeks to see if it will come into range. It can take time for moisture to be driven out and stresses to be relieved. If you have to go into it, it comes apart very easily. Just be very careful not to break the flask. You probably couldn't get a replacement. Regards. Max. K 4 O D S.

It seems to work pretty well. Not to surprisingly it's drifted a bit over the last 35 years. It's right at one end of it's 2.7x10^-7 tune range. From what I can see in the manual there's an adjustment on the crystal board that might bring it back onto frequency. Since getting there involves disassembling the dewar flask / oven combination I'm a little hesitant to dive right in. Has anybody torn into one of these before? If so what am I likely to run into? Everything I can see is wide open and very easy to work on. I'm hoping the oven is built the same way. Thanks!

Depends on what he wants to do. If he wants to write his own apps for the counter (or use mine) the Prologix controller will work fine.

If he wants to run existing commercial software like Labview he is likely better off buying a used National Instruments adapter on eBay, though.

I have the Ethernet version. They're nice for quick and dirty stuff and the USB / Ethernet versions can be used on laptops (Ethernet can be used on any computer that can telnet across the wire). You get to write your own software to use them or use EZGPIB (and write your own software).

Re: [time-nuts] Prologix GPIB controllers
Brice-- Wonderful product! Combine it with the EZGPIB software and KE5FX's packages, and you're set. EZGPIB -- http://ulrich-bangert.de/html/downloads.html KE5FX -- http://www.thegleam.com/ke5fx/ Both run under windows (I'm running them under VMWare on OSX, currently with Lady Heather on the secondary display showing how my Thunderbolt is doing with the quieter power supply). EZGPIB lets you get up to speed quickly in dealing with GPIB devices. KE5FX has a number of very useful tools that he's written, as well as pointers to more. One of the great uses for EZGPIB is to go out and enumerate your GPIB (HPIB) devices -- so if someone has changed the default address, it's one call in EZGPIB to scan the address space and let you know what's out there (with the exception of write-only devices like the 59306A relay box). 73 de K6RTM Bob in Silicon Valley k6...@arrl.net (but k6...@comcast.net works too) --- Message: 9 Date: Sun, 1 Aug 2010 20:18:01 -0400 From: Heathkid heath...@heathkid.com Subject: [time-nuts] HP 5335A and HP-IB (GP-IB) To: Discussion of precise time and frequency measurement time-nuts@febo.com Message-ID: bae12857a7b84a4494ffab0bbabbd...@d1x25bd10 Content-Type: text/plain; format=flowed; charset=iso-8859-1; reply-type=original I just purchased a HP 5335A and would like to know the group's opinion on the following: http://www.sparkfun.com/commerce/product_info.php?products_id=549 73 Brice KA8MAV ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Re: [time-nuts] HP 5335A and HP-IB (GP-IB)
I do not have a 5335A, but... I use a ProLogix USB-GPIB adapter on a HP5370. I am not doing anything fancy, no real controlling. I set the GPIB on the 5370B to talk, then use John Miles GPIB Configuration program for the adapter. John KE5FX is on this list and has a web site with several GPIB programs that work with this adapter. After running the configuration program, you close it, then bring up a terminal emulator - HyperTerminal built into Windows - and capture the data. If you are going after Time Interval /Allan Variance, etc - data, there are two free programs out there, Alavar, and Plotter. Plotter is written by Ulrich Bangert , who is also on this list and also has a few other programs of interest. In my case, it is stupid simple and works great, works every time. I also had a Softmark controller - It would not play with the 5370B - I believe the SOftmark is set up to work only with SCPI capable instruments, which is the newer instrument protocol. It did work with a HP53131A - but you don't need it, the 53131A has GPIB and RS232, and you can get about the same data out of both ports - but the GPIB port is very fast, if you need to acquisition data at a high rate. My SOftmark card has been in the drawer for the last three years - if anybody wants it, I can probably make them a good deal on it - if there is an interest, please contact off list.

Does anybody know if the NI instruction set is copyright? Otherwise, I can see no good reason for all controllers not being interchangable. -John I do not have a 5335A, but...

Re: [time-nuts] Prologix GPIB controllers
Bob, Thanks to you and all the other people on this wonderful list (on and off list) who have recommended this product... done. Ordered with Next Day Shipping. Got a lab coat too (couldn't pass it up... the one's I have at work are disposable as getting someone to clean them is near impossible or actually too expensive as it's a bio-hazard) as well as a bunch of other stuff that was just sitting in my SparkFun cart. Oh well... fantastic excuse for placing the order and I'm sure my wife will LOVE me wearing a lab coat around the house. ;) Grabbed a few more (okay... a dozen) logic level converters too while I was at it. It seems these days... everything I'm working with is either 1.8v (Gumsix Overo), 3.3v (Arduino and Propeller), or 5v (everything else) and nothing likes to talk to each other without a logic level converter. Anyway, I'm looking forward to being able to getting the HP-B/GP-IB data out of the HP 5335A (and other equipment to come) and being able to log it and do something useful (unlike wearing the lab coat around). hehe Thank you all... I'm on the right path (I think) with measuring time but it seems to lead to insanity. Is this correct? 73 Brice KA8MAV - Original Message - From: k6...@comcast.net To: time-nuts@febo.com Sent: Sunday, August 01, 2010 11:09 PM Subject: Re: [time-nuts] Prologix GPIB controllers Brice-- Wonderful product! Combine it with the EZGPIB software and KE5FX's packages, and you're set. EZGPIB -- http://ulrich-bangert.de/html/downloads.html KE5FX -- http://www.thegleam.com/ke5fx/ Both run under windows (I'm running them under VMWare on OSX, currently with Lady Heather on the secondary display showing how my Thunderbolt is doing with the quieter power supply). EZGPIB lets you get up to speed quickly in dealing with GPIB devices. KE5FX has a number of very useful tools that he's written, as well as pointers to more. One of the great uses for EZGPIB is to go out and enumerate your GPIB (HPIB) devices -- so if someone has changed the default address, it's one call in EZGPIB to scan the address space and let you know what's out there (with the exception of write-only devices like the 59306A relay box). 73 de K6RTM Bob in Silicon Valley k6...@arrl.net (but k6...@comcast.net works too) --- Message: 9 Date: Sun, 1 Aug 2010 20:18:01 -0400 From: Heathkid heath...@heathkid.com Subject: [time-nuts] HP 5335A and HP-IB (GP-IB) To: Discussion of precise time and frequency measurement time-nuts@febo.com Message-ID: bae12857a7b84a4494ffab0bbabbd...@d1x25bd10 Content-Type: text/plain; format=flowed; charset=iso-8859-1; reply-type=original I just purchased a HP 5335A and would like to know the group's opinion on the following: http://www.sparkfun.com/commerce/product_info.php?products_id=549 73 Brice KA8MAV ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
Re: [time-nuts] HP 5335A and HP-IB (GP-IB)
You can't copyright an instruction set. Any patent protection NI may have had would have expired long ago. There is nothing preventing anyone that is willing to go to the development effort from making a NI clone, and several companies existed doing just that. -Chuck Harris J.

Re: [time-nuts] Z38xx and z3805
Hi Bob, I have a Z3801A and I am not sure whether the SCIP commands are the same as for the Z3805A. There must be some differences related to the channel numbers and serial post configuration at least I would expect. I think the following apply. You need to not only be able to provide a position, as was suggested, or from a survey, but to also prevent site survey from starting up at power on. Survey at start is default, at least on the Z3801A, and from what you say, I suspect your box does the same. If a position is specified, or the survey completes OK, the unit should go to position hold mode automatically. To check. :GPS:POSition:HOLD:STATe? To specify what startup mode you want :GPS:POSition:SURVey:STATe:POWerup ON or OFFON forces a survey. to check :GPS:POSition:SURVey:STATe:POWerup? If it is turned off the receiver will use the last valid position it has. This might be the default , (Korea) if the eprom is shot. hope that helps, Mike Le 02/08/2010 00:42, Bob Camp a écrit : GPS:POS N,DD,MM,SS,W,DD,MM,SS,ALT ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
