[:SOURce]:RADio:CUSTom:DATA <Mode>
Function: This command is used for setting the data sources of the baseband modulation signal,
which include PN9, PN11, PN15, PN16, PN20, PN21, PN23, FIX4, P4, P8, P16, P32,
P64 and PRAM.
Setting format: [:SOURce]:RADio:CUSTom:DATA PN9|PN11|PN15

Query format: [:SOURce]:RADio:CUSTom:DATA?
Parameter:
<Mode> Discrete data. For data source of baseband modulation signal, please refer to the format of
set command.
Example: :RADio:CUSTom:DATA FIX4
The baseband data source is set to Fix 4.
Reset status: PN9

[:SOURce]:RADio:CUSTom:DATA:PARM <S>
Function: When the data source of real-time baseband of the signal generator is set to File, this
command is used for selecting the data source code file, which must be stored under
D:\1465data\user\
DataSrc, with filename extension of ―.src‖. This command is used for
setting only.
Setting format: [:SOURce]:RADio:CUSTom:DATA
Parameter:
<S > Name of selected data source code file, including filename extension.
Example: :RADio:CUS
Tom:DATA:PRAM ―Test.src‖
Selected data source code file is ―Test.src‖.

[:SOURce]:RADio:CUSTom:FILTer <Mode>
Function: This command selects the baseband pre-modulation filter types of the signal generator,
including: RNYQuist, NYQuist, GAUSsian and RECTangle. RECTangle is applicable
to digital FM signal, such as FSK and MSK. See the command
―
:RADio:CUSTom:MODulation[:TYPE]
‖.
Setting format: [:SOURce]:RADio:CUSTom:FILTer RNYQuist|NYQuist |GAUSsian| RECTangle
Query format: [:SOURce]:RADio:CUSTom:FILTer?
Parameter:
<Mode> Discrete data. Baseband pre-modulation filter types are as follows:
RNYQuist Root Nyquist filter,
