2.7.2 Level Control
As shown in the example, the sensor measures a proportional power in defined time
intervals, derived from a coupler. It considers optionally the given S-parameters and
returns the results to the generator. The signal generator compares the measured level
with the set value and adjusts its output level accordingly.This allows you to control the
external signal level continuously and reliably reach a constant input level at the DUT in
real time.
In practice, an RF splitter is needed to split the RF signal.One of them is connected to the
DUT and the other is connected to the power meter. The signal source is for acquisition
and compensation.Power compensation can be used to minimize cable losses, the
attenuation of passive networks, and the amplification of the signal by a power amplifier
and the frequency response of each device in the link as the frequency changes.
Note: When the function is turned on, the frequency or level sweep and the power sensor
measurement function will be turned off, and vice versa.
2.7.2.1 SensorState
The default is ―off‖. Activate/deactivate level measurement by the power sensor.
 On:Turn on the power sensor level control function, and the measurement control
refreshes the power sensor measurement value in real time.
 Off:Turn off the power sensor measurement function.
