1137.7470.12 6.2 E-7
Commands as per IEEE 488.2
The sensor supports a subset of the possible setting commands and queries (Common Commands and
Queries) in line with IEEE 488.2.
*IDN? – Identification Query
*IDN? returns a string with information on the sensor's identity (device identification code). In addition,
the version number of the installed firmware is indicated. The string for a sensor of type R&S NRP-Z21
has the following structure:
ROHDE&SCHWARZ,NRP-Z21,<serial number>,<firmware version>
<serial number>: Serial number in ASCII
<firmware version>: Firmware version number in ASCII
*RST – Reset
*RST sets the sensor to the default state, i.e. the default settings for all test parameters are loaded.
*TRG – Trigger
*TRG triggers a measurement. For this purpose, the sensor is in the WAIT_FOR_TRIGGER state and
the source for the trigger event is set to BUS (TRIGger:SOURce BUS).
*TST? – Self Test Query
*TST? starts a selftest and returns 0 (no error found) or 1 (an error has occurred). The selftest
comprises the following functions:
• RAM test
• Operating voltages
• Temperature measurement
• Calibration data set
• Noise
• Zero-point offsets.
