reference calibration factor automatically. Offset, relative and duty cycle settings
are ignored during calibration.
The command used to calibrate the power meter is:
CALibration[1|2]:AUTO ONCE
The command assumes that the power sensor is connected to a 1 mW reference
signal. It turns the power reference oscillator on, then after calibrating, returns the
power reference oscillator to the same state it was in prior to the command being
received. It is recommended that you zero the power meter before calibrating.
Calibration sequence
This feature allows you to perform a complete calibration sequence with a single
query. The query is:
CALibration[1|2][:ALL]?
The query assumes that the power sensor is connected to the power reference
oscillator. It turns the power reference oscillator on, then after calibrating, returns
the power reference oscillator to the same state it was in prior to the command
being received. The calibration sequence consists of:
– zeroing the power meter (CALibration[1|2]:ZERO:AUTO ONCE), and
– calibrating the power meter (CALibration[1|2]:AUTO ONCE).
The query enters a number into the output buffer when the sequence is complete.
If the result is 0 the sequence was successful. If the result is 1 the sequence failed.
Refer to "CALibration[1]|2[:ALL]?" on page 248 for further information.
The CALibration[1|2][:ALL] command is identical to the
NOTE
CALibration[1|2][:ALL]? query except that no number is returned to
indicate the outcome of the sequence. You can examine the Questionable Status
Register or the error queue to discover if the sequence has passed or failed.
Refer to "Status Reporting" on page 96 for further information.
