Thanks to both of you. I will open it up tomorrow and check out the
attenuator.

You would be looking for transmission loss. If there is a problem
with the attenuator, it could present very high attenuation.
Safest way to do this is to set the SA for zero attenuation, connect a
power meter or another SA to the OUTPUT of the 1st SA attenuator and a
signal generator to the input of the attenuator. Then cycle the
attenuator through its various attenuation settings and record the
results.
A bit more dangerous method would be to inject a signal AFTER the
input attenuator (I would start quite low -30 or -40 dBm) and see how
the SA performs.
If the measured attenuation differs from the actual attenuation
significantly, you have a problem.

Are you talking about the HP 8594E's INPUT attenuator? What would I
be looking for?
