CALibration:TEST:REFerence?
The thermal power sensors are equipped with an additional test heater.
Queries the reference value of the power difference in W when measuring with the
external heater enabled and disabled. The reference value is determined during the
calibration process and stored in the calibration data set.
Usage:
Query only
CALibration:USER:DATA
<caldata>
Transfers the user calibration data set, which mainly contains S-parameter sets for
user-specific devices. The query returns the data as it was downloaded to the power
sensor before.
After downloading of a new user calibration data set to the power sensor, the current
S-parameter correction settings become invalid. Safe operation of the power sensor is
only possible if the
SELect
and
STATe
commands are repeated after download. See

Parameters:
<caldata>
<block_data>
CALibration:USER:DATA:LENGth?
Queries the length of the user calibration data block.
Usage:
Query only
CALibration<Channel>:ZERO:AUTO
<state>
Performs zero calibration.
Turn off all test signals before zeroing. An active test signal during zeroing causes an
error.
While zero calibration is in progress, no queries or other setting commands are
allowed, since the command is synchronous. Any communication attempt can run into
a timeout.
After zero calibration, query the static error queue (
responses are possible:
●
0
No error, the zero calibration was successful.
●
-240
Warning, zero calibration failed. See also the example.
