Enable Logging
Activates recording of R&S NRP-Z power sensor readings.
If enabled, every value measured by a connected power sensor and indicated in the
user interface, is written to a log file. Per measurement the function logs the measured
value (2 readings when you work with peak sensors), the sensor type and the mea-
surement time (time stamp).
The function automatically creates the file name
SensLog<n>.txt
and stores the file
in
*txt
format under
D:\user\SensorLogging
on the hard disk. You can enable
logging for each connected sensor separately. If enabled, one file per sensor is written.
Note: This specific function is intended for measurements with long time intervals, or if
there is a risk that the connection to the sensor can be interrupted and you need the
data for reconstruction.
The simplified recording function continuously writes the values in the file of the corre-
sponding sensor number, like
Sens1Log.txt
. When you start a new measurement,
the existing data will not be overwritten, but added to the file.
If you use this function, it is recommended that you regularly remove the files from the
hard disk, since they require storage capacity.

5.5.11 Analog Modulation
5.5.11.1 Overview
The R&S SMJ provides the analog modulations amplitude modulation (AM), broad-
band amplitude modulation (BB-AM) and pulse modulation (Pulse) for the basic unit
(R&S
SMJ+ frequency option R&S SMJ-B10x) without additional equipment options.
However, the analog modulations frequency modulation (FM) and phase modulation
(PhiM) require option R&S
SMJ-B20 (FM/PhiM Modulator).
Settings for the modulation are made in separate modulation menus. These menus
can be accessed in the block diagram by way of the "RF/A Mod" function block, or by
means of the menu with the same name which is opened using the MENU key.
Enabling/Disabling Analog Modulations using the MOD On/Off Key
The MOD ON/OFF key switches the modulations on and off.
MOD ON/OFF
Press the MOD ON/OFF key to enable/disable analog modulations.
Pressing the key again restores the status that was active before the last switch-off.
"MOD OFF" is displayed in the info line of the header next to the "Level" field.
