Sounds like you on the right track , If you lucky the relay is just
stuck as you say and you might exercise your way out of it... could
also have suffered from input overload ...a bit harder to fix
???
Hi All,
I just acquired an E4406A and put it on my bench. It
seems to work fine except that it is consistently
reading 15dB low.
Poking around I found a control for the input
attenuator and that seems to have no impact on the
measured value. From there I looked at the services/test
guide and ran through the 50MHz Input Attenuator
Accuracy test and that showed no change so I think that
the attenuator is stuck.
Before I start pulling this apart I thought I might
check in to see if I'm missed something in the system
settings that might cause this?
Thanks,
TonyG
