4. Use the Set Offset command to measure and save the DC voltage of the reflected-pow-
er test point at 0 W output power.
To abort, exit the Trigger: Set info window by pressing Back. To continue, confirm by

Explanation
Measurement display
Current reflected power
Currently measured DC voltage of the test point
Setting of a warning threshold for the reflected power
Forward power/50 (corresponds to the maximum reflected power)
Used to select a dB value for the warning threshold referenced to the
reflection switch-off threshold which is at a return loss of -17 dB (corre-
sponding to a reflected power/forward power ratio of 1/50)
Execution of calibration and display of the results
Internal measurement value of the nominal value
Deviation from the zero value of the power display
Used to calibrate the internal measurement system. Set Gain stores the
internal measurement value for the entered (measured) nominal value.
Used to calibrate the zero point as of which the externally measured
power is displayed. Set Offset calibrates the zero point.
