Agilent X-Series Signal Generators SCPI Command Reference 387
Real–Time Commands
Custom Subsystem–Option 431([:SOURce]:RADio:CUSTom)
Key Entry FIX4
Remarks FIX4 must be already be defined as the data type. To change the data type, refer to
“:DATA” on page 386
.
:DATA:PRAM
Supported N5172B/82B with Option 431
[:SOURce]:RADio:CUSTom:DATA:PRAM "<file_name>" [:SOURce]:RADio:CUSTom:DATA:PRAM?
This command selects a pattern RAM (PRAM) file as the pattern data type for a custom
communications format.
"<file_name>" This variable designates the PRAM file in the signal generator’s volatile memory
(WFM). Refer to “File Name Variables” on page 13 for information on the file name
syntax.
Key Entry PRAM File
Remarks Selecting this data source forces the burst source to INTernal to allow framing
control.
The PRAM file must reside in the signal generator’s volatile memory (WFM) in
order to be accessed by this command.
:DENCode
Supported N5172B/82B with Option 431
[:SOURce]:RADio:CUSTom:DENCode ON|OFF|1|0
[:SOURce]:RADio:CUSTom:DENCode?
This command enables or disables the differential data encoding function.
*RST
0
Key Entry Diff Data Encode Off On
Remarks
Executing this command encodes the data bits prior to modulation; each modulated bit
is 1 if the data bit is different from the previous one, or 0 if the data bit is the same as the
previous one.
:EDATa:DELay
Supported N5172B/82B with Option 431
[:SOURce]:RADio:CUSTom:EDATa:DELay?
This query returns the amount of delay (in symbols) from the external data input to the beginning of
the symbol on the I OUT and Q OUT rear panel connectors and the front- panel RF OUTPUT
connector.
Remarks
When the format is turned off, the delay value is unchanged; the query will return the
same delay value if the format is on or off.
