Re: 3586B Selective Voltmeter Help trouble shooting
I have an A70 board, so not a switch problem, I have removed, wiped doen the edge connector, it already looked good and reseated it. That didn't help. As a troubleshooting method can I remove the A70

Re: 5342A: blown sampler?
I’ve done the connector change and, using a good quality SMA, I have two 5342As that count reliably to 26GHz and one that just won’t count reliably above about 21GHz. I don’t have a 5343A to

Re: 5342A: blown sampler?
Hi Harke, oh, interesting. So the upgrade to 26 GHz, which would actually be a 5343A, changes only the connector? :-) This is funny, because I use a HP 8563E spectrum analyzer at work, which operates

Re: 5342A: blown sampler?
Hello Tobias, Congrats on the repair! Happy for you the sampler was fine! I can only comment on the frequency range. I have a number of HP equipment (including the HP5342A) that are spec'd to 20-22

Re: 5342A: blown sampler?
The connnector on the higher frequency model was 3.5 mm, not N. I don't know if there are other changes

Re: 5342A: blown sampler?
Hi all, problem solved: as I said, the counter was counting fine on the low frequency input, but on the high frequency input, it displayed only zeros. The reason was that a) the -5.2V operating

Re: 8568B YTO unlocked
Tobias, As G?ran said, 8568 and 8566 are different design. I have no knowledge of 8568 so I can only speak for 8566. In 8566, if the frequency span is less than 5mhz, YTO is phase locked during the

I tried an external reference without luck. I guess it is time to dig into the problem.

Re: 3586B Selective Voltmeter Help trouble shooting
One thing to note, is when the keyboard springs fail, the button feels dead, but can get stuck in a depressed position, which bothers the power on self test. If you have any dead keys, fix them

Re: 8566B PL1 Unlock, PL2 Unlock and Ref Unlock
Thanks, I'll try the external ref. I have a 3586b sitting next to it and that has the 10Mhz Oven in it. Maybe I can just run that in? I haven't checked the 3586B output and the input into

Re: 8566B PL1 Unlock, PL2 Unlock and Ref Unlock
First try the external reference again, to be sure whether the internal one is OK or not. In my experience, the (Ovenaire brand as I recall) OCXOs used in the 8566s have been quite unreliable (ovens

Re: 8568B YTO unlocked
Yes, I found it very impressive. The phase lock loop design(20/30, M/N and YTO loops combo) is shared by 8340/41, 8566, 8672 and possibly other sweepers and SAs too. Learned a lot by studying the

Re: 8568B YTO unlocked
Tobias, Look at page 9-49 in the 8568 service manual (Vol. 4). The section is called "RF Section Analog Troubleshooting". The problem you describe does not seem to me like it's YTO related. It
