Hi Nigel As you are in the UK and have access to Toolstation a very useful solvent for many purposes is their PVCu Solvent Cleaner. ?Its great for removing all sorts of unwanted residues and is does

Thanks for all the comments. I've actually ordered a new one from Digikey UK; bizarrely it's coming from the USA even though it's made in Switzerland and ordered from a UK company!!!! They had the

Hi Dave Thank you for your E mail from other E mails it appears this item is not supported by the normal 70900 local oscillators So only fit to stripe down for parts Could you post the clip on a site

I have the service manual and the CLIP for this module. Let me know if you have any specific questions. Thanks, David Slik VE7FIM wrote:

Since I can never tell what is 1 and what is 0 on these switches, here is a picture of the "Normal" setting for S400: I can't find any information on what positions 1-7 do. I do remember they have

I think you have option 089, or at least some of the required hardware. I see an R-channel switch in your picture. It's that gold plated microcircuit between the wide rainbow-colored ribbon cable and

Hi Vladan, Thanks for the thoughts on the options. How can I know if option 89 is available (hardware wise)? Being able to do mixer measurements (easily) would be really nice. I have no problem using

Derek, to me those pictures look like it's an option 007 + option 085 configuration (high power measurements).This means no bias-Ts, and it will be a bit of work to convert to 4-sampler. This option

Plugged in a Tektronix 7000 series counter (7D15 to be exact), on an extender. It wasn't working. I had the room lights dim for whatever reason, hopefully to see anything that was unhappy. Everything

Hello, I've just acquired an HP 8720D which was "working until one day it stopped". I tried turning it on and the machine started continuously rebooting every ~6 seconds. Nothing is ever displayed to

Hello, Apparently there are some early version A4 Log Amp/Cal Oscillator? and A5 IF Boards that were used in the 8563A Spectrum Analyzer.? I must have a later version and would like to know if there

More about this common type of failure: https://www.eevblog.com/forum/repair/hp3458a-schaffner-mains-line-filter-failure/ I had one go off in a HP3457A. Took out 16 A line breaker, created a jet of

I would suggest *not* replacing with the original. Schafner filters are fine in the USA, but double the mains voltage, and they are stink bombs. I would not use a used or old filter as a replacement.

Yes, totally normal behaviour! Problem is the filter caps are pre the power-switch/voltage selector and they just give up eventually. A lot of my equipment was bought in the USA so those caps have

Hi It is preferable to use a newly manufactured unit when in use in Europe, the voltage ratings of the filter capacitors has been raised. 73 George G6HIG

Hi, that's, unfortunately, normal. They go up in smoke after some age. I believe (if you are brave) you can use the Equipment afterwards, normally they fail OC (at least mine have so far), but I would

All of this trouble due to a shorted 390 pF capacitor!
