:CALCulate{1-16}[:SELected]:GCOMpression:INDicator[:STATe]?
Description
The command turns on/off the compression point indicator on the active trace of the indicated channel. The instrument must be in Power Sweep CW mode. The query outputs the on/off status of the compression point indicator on the active trace of the indicated channel. The instrument must be in Power-Sweep CW mode.
Cmd Parameters

:CALCulate{1-16}[:SELected]:GCOMpression:PARameter <char1>
:CALCulate{1-16}[:SELected]:GCOMpression:PARameter?
Description
The command sets the S-Parameter for gain compression on the active trace of the indicated channel. The instrument must be in Power-Sweep Swept-Frequency mode. In the indicated channel, the query outputs the S-Parameter for gain compression on the active trace. The instrument must be in Power-Sweep Swept-Frequency mode. This value is not reset by an instrument reset.

Description
The command sets the gain compression point value on the active trace of the indicated channel. Instrument must be in Power Sweep CW mode or in Power Sweep Swept Frequency mode. The query outputs the gain compression point value on the active trace of the indicated channel. Instrument must be in Power Sweep CW mode or in Power Sweep Swept Frequency mode.
Cmd Parameters

:CALCulate{1-16}[:SELected]:GCOMpression:REFerence <char1>
:CALCulate{1-16}[:SELected]:GCOMpression:REFerence?
Description
The command sets the reference type for gain compression on the active trace of the indicated channel. Instrument must be in Power Sweep CW mode or in Power Sweep Swept Frequency mode. There are three types of gain compression references that can be set:
• MAXGain = Maximum power gain at the highest point in the gain curve output.
• PHOLd = The reference value will be that for the S-Parameter such as S21 set by the :CALCulate{1-16}[:SELected]:GCOMpression:PARameter command.
• PINput = Input in dBm, this is the reference is value set for the selected S-Parameter which occurs when the input power is set to the value of gain compression reference value.
The query outputs the reference type for gain compression on the active trace of the indicated channel. Instrument must be in Power Sweep CW mode or in Power Sweep Swept Frequency mode.
Cmd Parameters
<char1> MAXGain | PHOLd | PINput
Query Parameters
<char1> MAXG | PHOL | PIN
Range
NA
Default Value
MAXG
