Using Power Meter
Introduction
The Power Meter of the CellAdvisor 5G uses power measurement based on spectrum measurement results to provide an accurate
power measurement result unlike a general spectrum analyzer, of which power accuracy may be degraded if the span is set too
wide.
The power meter also provides Pass/Fail indication with user-defined lower and upper limits.
Display Maximum/Minimum of Amp/Scale can be measured on screen.
