[time-nuts] Boatanchor docs: HP AC-4 counter module manual

O Nuts of Time, I was recently asked to make a big PDF file of the HP AC-4 counter modules manual that I have had on my website for a few years as a series of jpeg files. So I did... http://www.nixiebunny.com/hpac4/hpac4.pdf These modules are used in the ancient HP 521 to 524 series of counte

Re: [time-nuts] HP 3456A stability upgrade

I need to clarify something about my earlier posting regarding the 3456A upgrade. The upgrade involves more than dropping in a new part; there are other circuit changes also required. Lion Electronics does the conversion, but doesn't supply the parts separately (after all, he's in business!).

Re: [time-nuts] Lady Heather Update

I'm trying to bring the Win32 version up to date with the graphical version, but am dealing with a bug that apparently puts the Thunderbolt into some kind of mode where it returns junk data over the serial line. My Win32 build runs for a minute or so, draws some graphs that don't make sense, and t

[time-nuts] Lady Heather Update

Hello again Magnus, If the program is started up and it is not seeing the Tbolt on the COM port you should see the "Log: OFF" indicator, two lines of text that are the plot area header, and the plot axes/grid. Pressing the SPACE bar should bring up a help screen in place of the plot grid.

Re: [time-nuts] HP 4352A/B with different signal generator

There's a 4352B on ebay for a $1K start bid, but there's a reserve. There's a 4352A for $1999 Buy it Now with an "Or Best Offer" option. In general, this is an absolutely great time to get modern test equipment at very low cost. With the economy down, everybody wants to get rid of inventory. I j

[time-nuts] HP 3456A stability upgrade

For you volt-nuts out there... There's a fellow in California, John Lion (LionElectronicLabs at BigPlanet dot com) who has a supply of temperature-chamber-aged and then hand-selected LM-199AH references that he will install into an HP 3456A DMM for a fairly reasonable price. I don't know how m

Re: [time-nuts] HP 4352A/B with different signal generator

Hi Matt: Where can I get one for that price? The Sig Gen phase noise is the driving spec since it needs to be better than the phase noise of the VCO you are measuring. Have Fun, Brooke Clarke http://www.prc68.com Matt Ettus wrote: > Does anyone know if it is possible to use the HP4352A/B VCO/

[time-nuts] HP 4352A/B with different signal generator

Does anyone know if it is possible to use the HP4352A/B VCO/PLL analyzers with signal generators other than the 8665A? What is involved? I have a sig gen which is plenty good, so buying an 8665 just to go with a 4352 (which you can now get for about $1K) seems like a waste. Thanks, Matt _

Re: [time-nuts] Lady Heather Update

Hi all, I am running an AMD Duron 700MHz running W98SE when run the program opens a DOS window but crashes the video monitor until the program is stopped with the escape key. So some of the problems may be with the monitor parameters which may not support the high res that a lot will be running eve

Re: [time-nuts] Lady Heather Update

I had similar probs with trying to run on WinxP Home – just a few coloured dots at the top of a black screen. But then I read the words the compiled version is for DOS/WIN98 and mayby WIN ME, WIN/NT DOS mode on systems with a VESA compatible video BIOS. Martin G8BHC 2009/1/31 Magnus Danielson
