10.6.16 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.
The figure below shows the relations between the available trigger settings.
The measurement is always on trace 1, either with the peak detector to determine the
peak power or the RMS detector to determine the RMS power. Overall, you can config-
ure the measurement independent of the instrument setup with the commands listed
below only, which results in faster measurements.
The Pulse Power measurement is incompatible to other measurement functions (e.g.
marker functionality or statistics). If you use a command that controls those functions,
the R&S FPL1000 aborts the Pulse Power measurement.
The R&S FPL1000 also aborts the Pulse Power measurement if you end the remote
session.
The commands can be used in two different ways.
●
Instrument setup, measurement and querying of the results in a single command
line. With this method, there is the least delay between the measurement and the
result output. However, it requires the control computer to wait for the response
from the instrument.
