Use the "Setup >" Chapter 5.2.3.5, "NRP-Z Info/Update" , on page 107 dialog to update
the sensor software.
Remote command:
SENSe<ch>[:POWer]:STATus[:DEVice]?
on page 401
Type
Indicates the type and the serial number of the connected R&S NRP-Z power sensor.
The sensor type is automatically detected.
Remote command:
SENSe<ch>[:POWer]:TYPE?
on page 434
SENSe<ch>[:POWer]:SNUMber?
on page 401
State
Activates/deactivates level measurement by the power sensor.
The local state is set with the
INIT
command. Switching the local state off enhances
the measurement performance.
In remote control, the sensors are set up using the
SENSe
commands. The remote
measurement is triggered by the
READ
query which also provides the measurement
results. The state is not influenced by these commands, measurements results can be
retrieved with local State on or off.
The sensor is selected by suffix 1, 2, 3 or 4 in key word
SENSe
or
READ
of the com-
mand header.
Suffix 1 denotes the sensor connected to SENSOR, suffix 2 the one at the first USB
interface, and suffix 3 and 4 are assigned to the sensors at the following USB interfa-
ces. The suffix is identical to the index which is assigned automatically to each sensor
upon connection.
In order to detect all connected sensors the state of all four connectors (i.e. SENsor1/
SENSor2/SENSor3/SENSor4) must be checked.
To query the availability of a sensor at a given connector, use the command
SENSe<ch>[:POWer]:STATus[:DEVice]?
on page 401.
Remote command:
:INITiate<ch>[:POWer]:CONTinuous
on page 392
