50|75
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>
[:SENSe]:CORRection:SA[:RF]:GAIN?
Description
Sets the external gain.
Queries the external gain.
Parameter

Default
<rel_ampl>
Consecutive Real Number
-120 dB to 120 dB
0 dB
Return Format
The query returns the external gain value in scientific notation. The unit is dB.
Example
The following command set the external gain value to 20 dB.
:SENSe:CORRection:SA:RF:GAIN 20
The following query returns 2.000000000e+01.
