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 (SYSTem:SERRor?). The following
responses are possible:
●
0
No error, the zero calibration was successful.
●
-240
Warning, zero calibration failed. See also the example.
Suffix:
<Channel>
.
1 to 4
Measurement channel if more than one channel is available.
Parameters:
<state> ONCE
Only valid parameter for this command.
0
Return value if no calibration is in progress.
*RST: ONCE
Example:
*CLS
CAL1:ZERO:AUTO ONCE
Performs zeroing. Takes several seconds.
SYST:SERR?
Query
-240
Response: Warning; Zero Calibration failed; Results Degrading.
8.11 Testing
The selftest allows a test of the internal circuitry of the power sensor.
Do not apply a signal to the power sensor while the selftest is running. If the selftest is
carried out with a signal being present, error messages can erroneously be output for
the test steps Offset Voltages and/or Noise Voltages.
TEST:SENSor? [<Item>]
Starts a selftest of the power sensor. In contrast to *TST?, this command returns
detailed information that you can use for troubleshooting.
