Hi there, We wish to know the uncertainties involving power meter calibration using the 11683A range calibrator. As per the Agilent note 11683A -90010, under...
Hi group, so, I have started with my HP 141T repair yesterday. Here is what I have done so far. I intend to use this as some sort of record of my proceedings....
An interesting observation from running the IAs on 16500B, 16500C, 16505A and 16702A. I've tried loading the state/timing setup into 16500B and I had some...
I'd be amazed if a 141T CRT faceplate failed. Congrats on finding the scope plugins, those are scarce as hen's teeth these days; I surmise they've all been...
Here is some confirmation regarding the IA files in the invassm.zip [snip] ... [snip] I can now confirm that the Inverse Assembler files are the only files...
A minor correction: I have the 8552B plug-in, not the A-Version. 4) Checking the supply A2 board I have made working copies of the schematics and component...
608F. I speculate that L and M, or at least L, came along after HP settled down on using A, B, etc, to identify major engineering revisions as opposed to...
Hi, My 54502a works fine now - with the addition of a 'new' attenuator, it works in glorious two channels. It doesn't quite pass the selftest .. Acq RAM Test...
Hi, I'm looking for a (free) schematic capture program that will enable me to draw and edit schematics. I do not need anything fancy, just op-amps, Rs, C's...
I use ExpressSCH. This has an extensive library and allows custom parts. I just use this for schematics. It is free and the learning curve is short. What ICs...
ExpressSCH will allow custom components. It has circles and lines that can be combined to form a custom part. Tubes would be no problem. Can be down loaded...
Hi Gang, The one I use is LTSpice, is has schematic capture and is a very good SPICE simulator as well. There is a very active Yahoo group for support as well....
Kicad .. it's free, GPL and works well. http://www.lis.inpg.fr/realise_au_lis/kicad/ (I also use Eagle, but someone bought me a licence for non-profit use for...
Hi John, personally I use Eagle (by CadSoft). The Free version is limited to a PCB 100 x 80mm, but has no limitation on parts count. What ever you choose, I'd...
John, look at http://tinycad.sourceforge.net/ and http://focus.ti.com/docs/toolsw/folders/print/tina-ti.html Derward Myrick KD5WWI ... From: J. Forster To:...
Hi John: For reverse engineering I use the schematic program from ExpressPCB.com AND their PCB layout program. They support up to 4 layers (two being Vcc and...
Hi, Don't laugh !! If somebody on list just bought the lot of 9 assemblies for the 8753D on ePay, and does not need the 08753-60146 Source, please drop me a...
John, Obviously LTSpice will do much more than just design capture, but it does do a decent job of schematics and it's free. Best Regards, Bob Groschen ...
Hi John, ... Probably overkill for what you want but KiCAD is worth a look for anyone who wants a good cost effective (i.e. free) CAE suite, and it has an ...
If the 100 volt supply is varying, it will affect the 248 volt supply regulation. Check the pass transistor pins for corrosion; I've seen high resistance...
I will soon be getting a 141T, 8556A, and 8556B Who knows, the $50 8555A i've had for about a year and that still has the HP cal sticker intact may even work...
Has Anyone seen a glimse of a servicemanual on the Web.... I Can't seem to find it. Have found the "Rapid-Repair manual but i dont have the box og spare parts....
