Target Level
Specifies the nominal level expected at the input of the sensor. The signal generator
adjusts the output power accordingly, in order to meet the target value at the sensor
input, and thus the power required at the DUT.
Remote command:
[:SOURce<hw>]:POWer:SPC:TARGet
Limit - RF Level
Sets an upper limit for the RF output power.
You can use it to protect your DUT from damage due to high input power. If you enter
an RF level above this value, the instrument limits the output power to this specified
value, and generates a warning message.
However, the level indication in the status bar is not affected.
Note:
The limit value is always effective, regardless of whether you work with "NRP-Z
Power Control" or not.
The value is not affected by an instrument preset (PRESET key),
*RST
and the "Save/
Recall" function. It is influenced only by the
and the factory value is
equal to maximum level.
Remote command:
[:SOURce<hw>]:POWer:LIMit[:AMPLitude]
Catch Range +/-
Sets the capture range of the control system.
Within the range:
Target Level +/- Catch Range
the power control locks and tries to achieve the target level. Readings outside the
range are not considered.
Remote command:
[:SOURce<hw>]:POWer:SPC:CRANge
Delay Time
Defines a waiting period between the level adjustment of the generator and the next
measurement of the power sensor.
With this parameter, you compensate any dead times in the controlled system.
Remote command:
Use Peak Power
Activates control by means of the peak power values, provided the power sensor sup-
ports this function. Otherwise, the dialog does not show this parameter.
Remote command:
Use SParameter - Power Sensors
Activates the use of the S-Parameter correction data of the connected power sensor.
For sensors with attenuator this checkbox is automatically checked.
