Anritsu FAQs

Using the pre-amp, I see the message AMP-SAT on the display, but no large signals on the graph. What's going on?

answer

More than likely, there is a large signal outside of your measurement span causing the pre-amp to saturate. The pre-amp is a broadband amplifier, with no tuning or filtering before its input. This is why we recommend the pre-filters in the optional accessories.
