I have a nice HP 437B Power Meter that is not working. It passes self
test OK, But the output from the Sensor (Good 8482A) displayed varies
all over the place. Even after zero preformed on Power meter. I
downloaded the Service manual from the Agilent web site. The manual is
missing what is called the service sheets. BD1 Block Diagrams and the
schematic sheets A3A,A3B,A3C,A4A,A4B,A4C. Anyone have these sheets in
PDF format.
I suspect a problem with the Analog board but would like more info
before I start poking around.
Thanks
