Re: HP 339A Distortion meter problem
I had an issue with my 339, where it would work in some switch positions but not others, and even depending on which direction the switches were moved (probably why I scored it so cheap!). I traced it

Re: Troubleshooting a 8591e with opt 130
Yves, Agreed, I won't touch any adjustment yet. Wouldn't surprise me though if a previous owner already did. Anyway it seems we are locking in on the issue thanks to all your help which is great. I

Re: Troubleshooting a 8591e with opt 130
Marco, Obviously, it seems that it is the LOG section that is lacking, since the LIN mode works with the correct RF level. It may be one of the gain controls in module A. I will look at the behavior

Re: Troubleshooting a 8591e with opt 130
Hey Gordon, Thanks for the additional info! For now I'll keep trying to fix it with this firmware installed, I like the HP logo more anyway. ;) Marco

Re: HP 8662A + 8663A Power Supply
My 8663 was a flea market "bargain" (well - not really) but it was repairable by replacing the inverter transistors with BUX48 as well as a bunch of electrolytic capacitors and some other components

Re: Troubleshooting a 8591e with opt 130
So considering all the RBWs with the Log path are off, should I search for a fault in the A14 Log amplifier Assy? Or do you still think it's somewhere in the filters? I could try to do the 7. Log and

Re: HP 339A Distortion meter problem
MG has some interesting alternatives, some even more expensive than the Deoxit offerings (!!). For instance, the 801B. I still rely mostly on the Deoxit, but in some cases (high impedance

Re: Connector identification
Hi Scott, I think you solved the mystery. OSMT connector has the right shape and dimensions. Ozan

Re: HP 339A Distortion meter problem
I was going to recommend De-Oxit as well - I haven't found any other cleaner that works as well, which seems to justify its higher-than-I-think-it-should-be price.? I usually use De-Oxit Gold, except

Re: Troubleshooting a 8591e with opt 130
Since the picture you send about BW5 etc went down to 300Hz, I assumed those were the standard RBW settings. But it sounds more plausible anyway that all the standard RBW have the issue and the ones

Re: Troubleshooting a 8591e with opt 130
Without option 130, the last resBW is 1kHz. With option 130: 300,200,100, and 30 Hz There a problem with standard resBW. De : [email protected]

Re: Troubleshooting a 8591e with opt 130
Marco, Both PCBs have the same part number. But in my case, the A13 label on the PCB was for the right location i.e. A13...A11 PCB with A11 location. So, I don't see any difference between the PCBs,

You will need to troubleshoot the synthesizer. Start downloading the CLIP from Keysight site. Ing. Patricio A. Greco Taller Aeron¨¢utico de Reparaci¨®n 1B-349 Organizaci¨®n de Mantenimiento

Re: Troubleshooting a 8591e with opt 130
I did a reseating of A13 and A11. Again found something interesting. The manual states A13 and A11 are identical boards but A13 is the one nearest to the PSU. In my analyzer A13 and A11 is written on
