POWer:MPR
The subsystem POWer:MPR combines the POWer and MODulation systems, i.e. it measures the
signal power vs. time and the scalar modulation parameters simultaneously. The subsystem contains
all commands for measurement control and for the output of measurement results; configurations such
as limit lines must be defined separately in the
POWer and MODulation systems .
The POWER:MPR has no equivalent in manual control where the power and modulation measurement
results are displayed separately.
Control of measurement – Subsystem POWer:MPR
The subsystem POWer:MPR controls the combined power and modulation measurement.
INITiate:POWer[:NORMal][:GMSK]:MPR Start new measurement
⇒
RUN
ABORt:POWer[:NORMal][:GMSK]:MPR Abort running measurement and switch off
⇒
OFF
STOP:POWer[:NORMal][:GMSK]:MPR Stop measurement after current stat. cycle
⇒
STOP
CONTinue:POWer[:NORMal][:GMSK]:MPR Next meas. step (only stepping mode )
⇒
RUN
Description of command FW vers.
These commands have no query form. They start and stop the combined power and modulation
measurement, setting it to the status indicated in the top right column. VV2.00
