CALibration[1]|2:AUTO <boolean>
This command calibrates the specified channel when
ONCE
is selected. The
command assumes that the power sensor is connected to a 1 mW reference
signal. The
0|OFF
parameter is only required for the query response and
is ignored in the command. If
1|ON
is selected, the error -224, “Illegal
parameter value” occurs.
For 8480 Series power sensors and N8480 Series power sensors with
Option CFT, the reference calibration factor used during this calibration
can be obtained from an active sensor calibration table or the value
entered using
CALibration:RCFactor
. The actual value used is the one
which was most recently set. For example, a value entered using
CALibration:RCFactor
is overridden if a sensor calibration table is
subsequently selected and enabled and
CALibration:RCFactor
overrides any reference calibration factor previously set from a sensor
calibration table. To determine the current reference calibration factor,
use
CALibration:RCFactor?
The E-Series power sensors and N8480 Series power sensors (excluding
Option CFT) have their sensor calibration tables stored in EEPROM
which means that the reference calibration factor is automatically
downloaded by the power meter.
Note
The power meter should be zeroed before calibration using the
CALibration:ZERO:AUTO ONCE
command.
