And we're back to the same old nonsense you pull on your own group. Go ahead and scrap it. We don't really care. Perhaps if you stuck to selling your over priced equipment on your own group rather than flooding this group we wouldn¡¯t have to put up with your BS.

You were, in fact, threatening. Deciding not to sell it because you won't get what you think it's worth isn't a problem, and that's nobody's business but yours.

However, the "scrap it is" part was inappropriate and uncalled for, and your meaning was plain and transparent to everyone here.

In case MY meaning wasn't plain, everyone here knew damn well exactly what you meant when you typed that. Back-pedaling and trying to dismiss it as an innocent bit of chat isn't going to work this time. And, given your history, I'm willing to bet the sob story about your health and how much you have to pay someone to pack up your outbound boxes isn't going to be met with much sympathy here.

You've done this many times, you've been doing it for years, you're notorious for it, everywhere, and everyone knows it. The number of private messages I receive about your posts is such that it raises my already-high blood pressure even higher.

Don't do it again. There will be no further warnings.

Re: 8590B low sensitivity problem

Richard
 

Martin? don't forget you can also check the sections of the attenuator as well, disconnect it from the mixer and terminate with a 50ohms,

each section of the attenuator will look close to 50 ohms .

If you have an RF millivolt meter or another SA , you can easily check it, but if you don't? you can resort to the good old multimeter,DMM.

a section blatted with too much RF will read higher, BTW when I say good old multimeter I was NOT referring to the hi ohms range on a Avo 8,

the current from modern DMMs is very low anyway.

You can probably repair damage to the attenuator if you find some, the 8590 was built to a reduce cost and performance

Workaround for 4396A power supply failure

 

I've had a dead 4396A sitting on my bench for a number of years. Recently I found an excellent thread (started 9/2020) on a Dutch forum that gave me enough information to finally fix my partially failed Toko 04396-61040 A40 pre-regulator module. Use Google Chrome to open this link and it should give you an option to translate Dutch to English (or another language)
?
Lots of good photos here and partially decoded schematics. My contribution was to figure out how to bypass the "shutdown 2" signal on the second switching regulator as a quick fix (see the A40 block diagram in the related 4286A service manual). Although you lose fan rotation and +5V overvoltage protection I didn't judge that to be a major issue in my case. The root cause was probably a bad opto or SCR but I didn't take the investigation that far.
?
Also in that thread is a discussion of replacing the A40 Schaffner mains input module when the internal caps (RIFA brand no doubt) let out the magic smoke. I've had this happen on the 4396A and also an 8657B.

This not forgotten.

The 9122C was picked up today. I have the other one still in my storage area.
Shipping charges are anywhere up to €80 depending upon where
and how. It seems however that the increased e-trading because
of Covid has saturated some shipping services. I don't think it will be a good idea
to try to ship anything before january 2021.

I will get back once I have figured out a way to receive the amount needed
for shipping.

There¡¯s probably some lore that perpetuates the ¡°RF is black magic¡± thing, and all sorts of myths get accepted into such lore.

There is a very nice Starlink customer terminal tear down video on YouTube (that device is a brilliant bit of engineering BTW) and a good vuunk of the comment section just goes to show that magical thinking is here to stay.
