Average Mode

This mode displays the average forward and reflected power.
Note: In average mode, the VSWR or system match can be dis-
played instead of the reflected power.

Peak Mode

This mode displays the peak envelope power.

Burst Mode

This mode displays the average power in a burst. The burst's duty cycle is
measured by the DPM.

Crest Factor Mode

The crest factor is the ratio of the forward peak power and the forward average
power. It is measured in dB.
Note: There are no additional controls in this mode.

CCDF Mode

The CCDF measures the percentage of time the power level is above a
threshold. To set the power threshold:
1. Press menu.
2. Select CCDF Limit from the Main Menu.
3. Enter new value.
