[:SENSe]:TGENerator:POWStats[:STATe]?
Title
Tracking Generator Absolute Power Statistic State
Description
Specifies whether the tracking generator absolute power statistic table is ON or OFF. If the value is set to ON or 1, the tracking generator absolute statistic table is turned on.If the value is set to OFF or 0, the tracking generator absolute statistic table is turned off.
The query version of the command returns a 1 if the tracking generator absolute power statistic is on and returns a 0 if the tracking generator power statistic is off.
Note that this command is ignored if the tracking generator output is off.
Parameter

Parameter Type
<boolean>
Default Value
OFF

Title
Tracking Generator Normalize State
Description
Specifies whether the tracking generator normalization is ON or OFF. If the value is set to ON or 1, the tracking generator normalization is turned on. If the value is set to OFF or 0, the tracking generator normalization is turned off.
The query version of the command returns a 1 if the tracking generator normalization is on and returns a 0 if the tracking generator normalization is off.
Note that this command is ignored if the tracking generator output is off.
Parameter

Title
Tracking Generator Transmission Statistic State
Description
(Only valid for Tracking Mode and Normalize On) Specifies whether the tracking generator transmission statistic is ON or OFF. If the value is set to ON or 1, the tracking generator transmission statistic is turned on. Turning on normalization triggers the normalization sweep, during which the sweep complete bit of the operation status is zero, and :STATus:OPERation? can be used to detect the completion of the normalization sweep. If the value is set to OFF or 0, the tracking generator normalization is turned off.
The query version of the command returns a 1 if the tracking generator normalization is on and returns a 0 if the tracking generator normalization is off.
Note that this command is ignored if the tracking generator output is off.
Parameter

Parameter Type
<boolean>
Default Value
