Hi Robert, Any joy on this?. I tried to get some boards from Rick, but he seems to have gone QRT ?? I need the Modulation Distribution Board and the I/O Board. I also am looking for the DC plug &

Hello Family, I have an 8921A that has a Cat5 connector on the back panel. Can I use this the connect a printer to output the Screen results of my measurements? The HPIB Socket is useless, as I do not

I did purchase a proper pcmcia card just in case but couldn't find anything on procuring the files, or even anyone who has a card to lend, thanks for the help so far. I did reseat everything and

a battery will not fix this . Re-flashing the firmware would be a good first step but that requires a PCMCIA card with that firmware ....latest is 6.04 IIRC. I do have card for 6.01 as well as a spare

Sounds like a Back Up Battery is needed. Regards Bill M.

Hello! Was hoping to get some assistance, I've been using this machine a lot a few years ago, I move and haven't set it up in a while, and now I get a non-recoverable firmware error: '$Header:

Alexandre - in all cases when it would not switch on, it was dry capacitors in power supply. Inside PSU are small PCB's mounted at angle to main PCB. Each are numbered. These are the caps to change:

Thank you for the replies on this subject of spares. I suppose that what I would figure to be a part that does fail, the multi-function knob, is not high on the list of failure, which is surprising

Good day, and welcome to this group. Over the years of working with relays of all kinds, including some very small signal relay like those used in RF test equipment, I've run into several occasions

Hi Alex, I have heard that the AC / DC Switch on the PSU can be swapped if you only use the set on AC. This forum has excellent Manuals, which you should download and memorize .. or perhaps Print out.

Alex, I've heard that the power button mechanism is troublesome for the 8920 & 8924c machines. The button is up front of course - but the actual device is at the rear of the unit. and has a long bar

I've worked on quite a few E8285A, 8935 (E6380 & E6381) & 8924E/C over the years. PSU / Regulator board CAPS are the most prolific failures. CRT/Plasma displays next. Several have had failed

Hello to the group, I have always maintained spare parts for any test equipment that I own, i.e. IFR 1200 SS, Fluke, and the like. Since I am new to the HP 8920B and have already done the LCD

Welcome. If the 8920B has the full frequency option (0.4-1000MHz) and thus relay RF module that is possible. Another possibility is a poor coaxial connection. Robert.

Good morning friends, Forgive me for the lack of experience to write here in the group, I have an HP8920B and it stayed for 6 months measuring 4db above in spectrum analyzer mode. Suddenly one day i

Your distribution amp will probably be happier with a sine-wave signal.

I realized that it is not the FS730 I have but rather the smaller one FS710: FS710 10MHz distribution amplifier ( https://www.thinksrs.com/products/fs710.html )

Thanks Rick. ? My 8920A works perfectly fine and runs through all the diags for the various modules without errors and all measurements I have checked are within specs. It is only the SA module
