Zeroing and Calibrating the P-Series Power Sensor
P-Series wideband power sensor’s do not need manual calibration and zero
routines performed. These are performed without removing the power sensor from
the source.
Zeroing
Zeroing adjusts the power meter’s specified channel for a zero power reading.
The command CALibration[1]|2:ZERO:AUTO [ONCE|ON|OFF|0|1] causes the
power meter to perform its zeroing routine on the specified channel when
enabled. This adjusts the power meter for a zero power reading with no power
supplied to the power sensor.
1|ON can only be used with a P-Series sensor. When 1|ON is enabled the zero is
maintained by a combination of zero on-the-fly for measurements and
temperature compensation.
Zeroing of the power meter happens automatically:
– When a 5 °C change in temperature occurs
– When you change the power sensor
– Every 24 hours
– Prior to measuring low level signals. For example, 10 dB above the lowest
specified power for your power sensor.
Calibration
The command used to calibrate the power meter is:
CALibration[1|2]:AUTO ONCE
It is recommended that you zero the power meter before calibrating.
