Arb Commands

Dmodulation Subsystem–N5172B/82B with Option 431 ([:SOURce]:RADio:DMODulation:ARB)

Remarks The modulation format should be active before executing this command. If this

command is executed before the modulation format is active, the entered value

will be overridden by a calculated factory default value. Refer to the command to

activate the modulation format.

:SETup

Supported N5172B/82B with Option 431

[:SOURce]:RADio:DMODulation:ARB:SETup?

This command selects the digital modulation format type or multicarrier, and turns multicarrier off

or on (see the MCARrier choice description).

The MCARrier choice selects multicarrier and turns it on. Selecting any other setup such as GSM or

CDPD turns multicarrier off. To select the multicarrier setup, see the “:SETup:MCARrier” on

page 264.

*RST NADC

Remarks For information on the file name syntax, refer to “File Name Variables” on

page 13.

:SETup:MCARrier

Supported N5172B/82B with Option 431

"<file name>"

[:SOURce]:RADio:DMODulation:ARB:SETup:MCARrier?

This command builds a table with the specified number of carriers and frequency spacing or retrieves

the setup stored in the specified user file.

The carrier type, number of carriers, and frequency spacing value are returned when a query is

initiated. The output format is as follows:

If a specific file is loaded and then queried, only the file name is returned.

The variable <freq spacing> is expressed in units of Hertz (kHz–MHz).
