Details
This function cannot be performed when the SG option is not installed.
SG setting and measurement are executed repeatedly until the target
level specified at target, range is reached within the count specified at
count. This is used for various measurements such as a spurious
measurement with specified output level.
In this application, the Reference Level and Attenuator settings are
calculated as follows from the Adjustment Target Level, Crest Factor,
and Correction value and are set automatically at the measurement
section. Using this application, the Attenuator is set so that the Mixer
Input Level become 0 dBm.
