Chapter 2 Command Systems for GPSA and RTSA Modes  RIGOL 
RSA3000E Programming Guide  2-133 
Example 
The following command sets the frequency interpolation mode to LINear.  
:SENSe:CORRection:CSET1:X:SPACing LINear 
The following query returns LIN.   
:SENSe:CORRection:CSET1:X:SPACing? 
:INPut:IMPedance 
[:SENSe]:CORRection:IMPedance[:INPut][:MAGNitude] 
Syntax 
:INPut:IMPedance 50|75 
:INPut:IMPedance? 
[:SENSe]:CORRection:IMPedance[:INPut][:MAGNitude] 50|75 
[:SENSe]:CORRection:IMPedance[:INPut][:MAGNitude]? 
Description
Sets the input impedance for voltage-to-power conversion. The unit is Ω. 
Queries the input impedance for voltage-to-power conversion.

50 
Remarks
If the output impedance of the system under measurement is 75 Ω, you should use a 75 Ω to 50 Ω adapter 
(option) supplied by RIGOL to connect the analyzer with the system under test, and then set the input 
impedance to 75 Ω.
Return Format
The query returns 50 or 75. 
Example
The following command sets the input impedance to 75 Ω. 
:INPut:IMPedance 75 or :SENSe:CORRection:IMPedance:INPut:MAGNitude 75 
The following query returns 75.   
:INPut:IMPedance? or :SENSe:CORRection:IMPedance:INPut:MAGNitude? 
[:SENSe]:CORRection:SA[:RF]:GAIN 
Syntax 
[:SENSe]:CORRection:SA[:RF]:GAIN <rel_ampl>
