CALibration:DATA:LENGth?
Queries the length in bytes of the calibration data set currently stored in the flash mem-
ory. Programs that read out the calibration data set can use this information to deter-
mine the capacity of the buffer memory required.
Example:
CAL:DATA:LENG?
Query
57392
Response
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

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.
●
