Hello,
I have written the following email about 3 month ago, no reply and I also
couldn't find any information on this thing. There must be some experts out
there who know this beast. If not here, where else? ...
I have found another mysterious (at least for me) HP box in my cellar: It's
labeled K-79-59992A Mixer/IF Amplifier. It has 3 BNC connectors on the
front panel labeled IF output / LO /RF and a IF bandwidth switch with range
from 25 Hz to 100KHz. I think it's a accessory for a spectrum analyzer??
Any ideas where it belongs to, what kind of IF is used (frequency), ect. ?
As always, ANY information greatly appreciated.
Hmmm, I don't have the documentation handy. But it sounds like the
box used for phase-locking an 8620 series sweeper plug-in to a 3555A
generator in the 8409 network analyser systems. I think I still have
an 8409 manual in the archive, I will see if I can find it.
59992A units were also common in several other systems built around
network analysers and 5345A counters. They can be seen in HP
catalogues in the early 80's but generally only as part of systems.
