[Test-Equipment] Interfacing HP 8569B and 8444A OPT 59 tracking generator

[Carl Walker]

Greetings. 

Lacking manuals for both the 8569B and 8444A, I'm curious if there's any
trickery I need to engage in to interface these two units together.

Since the analyzer only has a 1st LO output connector and no 3rd LO
output (as do my older 141T/8xxx plug-ins that I've used with this
tracking generator), it's puzzling how I'm supposed to get the two units
to play together. There is, of course, the always mysterious "AUX B" AMP
connector on the back panel of the analyzer that may hold clues to this
riddle.

Any help is appreciated.

Thanks,
