FM Subsystem

The FM subsystem controls the settings and parameters
associated with frequency modulated signal.

FM State

:FM:STATe ON|OFF|1|0

:FM:STATe?

This command toggles the FM state between ON and OFF.
However, applying a frequency modulation to the RF carrier
requires you also set MOD on.

See

“Modulation State Subsystem”

on page 137

The query returns the current FM state.

Range

ON(1), OFF(0)

*RST value
