[:SOURce]:RADio:CUSTom:POLarity[:ALL] <Mode>
Function: This command sets the phase rotation direction of baseband signal, including: Normal
and Reverse, signal is normally modulated in Normal mode; Q channel signal is
reversed to complete the reverse of carrier signal in Reverse mode.
Setting format: [:SOURce]:RADio:CUSTom:POLarity[:ALL] NORMal|INVert
Query format: [:SOURce]:RADio:CUSTom:POLarity[:ALL]?
Parameter:
<Mode> Discrete data. Phase rotation mode of baseband signal is as follows:
NORMal | 0: Normal,
INVert | 1: Reverse.
Example: [:SOURce]:RADio:CUSTom:POLarity[:ALL] INV
Reverse phase of baseband signal.
Reset status: NORM

[:SOURce]:RADio:CUSTom:DENCode <State>
Function: This command enables Differential Encode ON/OFF. When Differential Encode is turned
on, modulated bit is set to 1 if data bit is different from its previous bit; if data bits are
the same, modulated bit will be set to 0. For example, when data bit is 1010 and
Differential Encode is turned on, modulated bit is 1111.
Setting format: [:SOURce]:RADio:CUSTom:DENCode ON|OFF|1|0
Query format: [:SOURce]:RADio:CUSTom:DENCode?
Parameter:
<State> Boolean data is as follows:
ON | 1: Turn on Differential Encode,
OFF | 0: Turn off Differential Encode.
Example: [:SOURce]:RADio:CUSTom:DENCode 1 Differential Code ON.
Reset status: 0

[:SOURce]:RADio:CUSTom:VCO:CLOCk <Mode>
Function: This command is used for setting baseband sampling clock.
Setting format: [:SOURce]:RADio:CUSTom:VCO:CLOCk INTernal|EXTernal
Query format: [:SOURce]:RADio:CUSTom:VCO:CLOCk?
Parameter:
<Mode> Discrete datathat take following values:
INTernal: Internal sampling clock,
EXTernal: External sampling clock.
Example: [:SOURce]:RADio:CUSTom:VCO:CLOCk INT Internal sampling clock is selected.
Reset status: 0
