HP 4192A LF Impedance Analyzer -- Troubleshooting Problem
Hello All, I'm new to the board. I have a HP 4192A LF Impedance Analyzer with a tricky problem (at least for me) that I haven't been able to troubleshoot. The HP service manual is written around

Re: Firmware for HP8714B RF Network Analyzer
I don't know that particular VNA, but all those I have used have a few ways of uploading cal kit. 1) Keyboard entry 2) GPIB 3) floppy disk. I just checked the "VNA Calkit Manager" and it does not

Re: OT: tekmate software
If anyone could help me with getting the system software for a (working) Tekmate 2402A, I would be very grateful. Of course, I'd be willing to financially compensate. Raymond

Firmware for HP8714B RF Network Analyzer
HI! Must you have a firmware disc to add new calibration constants in HP8714B? It says so in the service guide, but there is a command in the 8714B by saving data from RAM memory to Eprom memory Dare

Re: Binding post repair?
I always assumed that those posts are the same standard ones used in much HP gear, which are threaded, and each individually attached to the assembly. I have a damaged one on a 3455A that I plan to

Re: HP 3562A
Joe, That's one thing I did forget to do on that board, usually it is the first thing. Only because it is the easiest.... I really could use an extender for this one, not much chance of making one as

Re: HP 3562A
Chuck, Just a thought but have you checked all the tantalum caps on the board? I have found some PCB's with 'on board regulators' with downstream capacitors shorted that 'killed' the board

Re: HP 3468 DMM battery change
Great to hear for both you and the meter. It's so easy to have that solder drop from time to time. Good thing is nothing serious happen with the meter. Jeff

Re: HP 3468 DMM battery change
I finally had time to get back to it tonight. Joe mentioned power supply voltages. I had checked random points to make sure the power supply was running but I failed to check all the voltages at the

Re: 8563E +28V shutdown/oscillates
I was suspecting overheat as well, but wasn't the case. Turns out it WAS low input voltage - there were 2 x 180uF 40V caps going bad in the low voltage side feeding the LM317 regulator. There are 4

Re: HP 3562A

Re: HP 3562A

HP 3562A
I recently purchased another 3562A analyzer, this one is late production I believe 1990. I have repaired two other units, earlier production (1984/85). Of course there is a major change between the

Binding post repair?
About a month ago I got a 3456A that had a few issues (test faults 4 and 7) including a really bent guard binding post. Trouble shooting the test errors had me going in circles, so I decided to look
