Hi there,
I have an 8921A that needs a Hi power
Attenuator. they seem to be out of production.
I live in Perth Australia and wondered if you
can advise a supplier for the Stripline type
50 Ohm (?100W) resistor that I can carefully
solder into the Heatsink Cavity. I appreciate
that I will need to do some Calibration to get
the unit back in Specification. I can see
plenty of Termination tpes, but they do not
have the two Tags.
Any help would be appreciated
Regards
William Macham

since this is an 8920A may be more
of a challenge since you need the calibrate
routine and data ( usually fixed for the most
part anyway) on an Epson type card.
Probably cheaper to just replace what you have
.
I have a number of those low power input
attenuators from upgrades as well if it is
defective and there are plenty out there.
Just use an external high power attenuator and
input the value in the settings screen ...will
correct the input and output levels ...one of
the nice things about the 892X.
Usually the low power option was pretty rare
in an 8920A...mostly the standard 60W and the
optional 100W out there.? 8920B's seemed to
have a lot more variance in that regard.
