Aperture Time ← Sensor Settings
If "Use Default Aperture Time > Off", defines the acquisition time per sensor.
For example, to obtain a sufficient low average value, set the aperture time exactly to
one modulation period.
Remote command:
:SENSe<ch>[:POWer]:APERture:TIMe on page 252
S-Parameter ← Sensor Settings
S-Parameter correction is used to mathematically shift the reference plane to the DUT
by considering the S-parameters for any components connected upstream of the sen-
sor.
The S-Parameter table can be changed with the S-Parameters tool, provided as part of
the free R&S NRP Toolkit software. For more information, refer to the manual of the
connected R&S NRP power sensor.

Enable Logging ← Sensor Settings
Activates recording of R&S NRP power sensor readings in a log file.
There is 1 log file per sensor. The log files are created automatically and filled in con-
tinuously. They are text files with predefined filename SensLog<n>.txt, where <n>
indicates the connected sensor. Log files are stored on the internal memory, in the
directory /var/sgs/SensorLogging.
Each log file contains the measured value (2 readings when you work with peak sen-
sors), the sensor type, and the measurement time (timestamp). Logged data is not
overwritten. When a new measurement is started, the collected logging data is appen-
ded in the log file.
Check the used disc space regularly and remove log files to maintain storage capacity.
Note: The logging function is intended for measurements with long time intervals. It is
suitable source for data reconstructions if the connection to the sensor was interrupted.
Remote command:
:SENSe<ch>[:POWer]:LOGGing:STATe on page 256
9.6 Pulse modulation
This section explains the pulse modulation settings of the R&S SGS. The equipment
layout for generating the pulse modulation signal includes the option Pulse Modulator
(R&S SGS-K22).
To configure and perform a pulse modulation, you need to select the modulation signal
source and provide the corresponding settings.
