CALibration[1..4|:ALL]:ZERO:AUTO[?] ON | OFF | ONCE
The
CALibration[1..4]:ZERO:AUTO ONCE
command performs zeroing using the signal at the
sensor input. The sensor must be disconnected from all power sources. If the signal at the input
considerably deviates from 0 W, an error message is issued and the command is aborted (SCPI error -
231, "Data questionable; ZERO ERROR").
When used as a setting command,
CAL[1..4]:ZERO:AUTO
accepts only the parameter
ONCE
(start of
zeroing);
OFF
is ignored and
ON
is not accepted. A query returns
ON
if a calibration is running, in all
other cases
OFF
.
The command is overlapping, i.e. other commands can be sent to the R&S NRP while one or more
calibrations are running.
Zeroing is recommended if
•
the temperature has varied by more than about 5 °C,
•
the sensor has been replaced,
•
no zeroing was performed in the last 24 hours,
•
signals of very low power are to be measured, for instance, if the expected measured value is less
than 10 dB above the lower measurement range limit.

CALibration[1..4|:ALL]:DATA[?] <block_data>
This command is used to read and write binary calibration data sets for the sensors.
