Making the Measurement
To make the power measurement, you zero and calibrate the power meter,
then set it for the frequency of the signal you want to measure. The power
meter automatically selects the calibration factor from the sensor
calibration table.
Note The following procedure details the calibration for channel A. To
calibrate channel B use the same procedure using the equivalent
channel B softkeys. To calibrate both channels, zero the power
meter using in step “2”, then follow this procedure for
channel A then repeat step “3” through to step “9” using the
equivalent channel B softkeys.
