Evaluating the measurement results
(Evaluation)

The

Duty Cycle

function is provided for evaluating the results in

Scope

mode. This function automatically displays the ratio of the average to the
maximum power level (Pavg/Ppeak), calculated for the displayed time
period. This evaluation can be used to determine the duty cycle of
transmitters.

To activate the Duty Cycle function:

⇒

Press the

Evaluation

softkey, then press the

Duty Cycle

softkey.

ª

The ratio Pavg/Ppeak is displayed in the upper information pane.
