14.5.16 Measuring the Pulse Power
All remote control commands specific to measuring the mean or peak pulse power
(e.g. bursts in various telecommunications standards) are described here. This mea-
surement is available via remote control only.
The Pulse Power measurement is a gated measurement that determines the power
over a particular number of pulses. The measurement is controlled by an external trig-
ger or the video signal. A separate trigger event is required for each burst included in
the measurement. In case of an external trigger source, the trigger level corresponds
to the TTL level. In case of a video signal, you can define any threshold.
