FM:INTernal:FREQuency?

[SOURce:]FM:INTernal:FREQuency? [MINMAX] queries the modulating frequency. Returns a value in hertz.

FM:INTernal:FUNCtion

[SOURce:]FM:INTernal:FUNCtion SINSQUTRIRAMP NOIS USER selects the shape of the modulating waveform. You can use the noise function as the modulating waveform. However, you cannot use the noise function or dc volts as the carrier waveform. The default is SINusoid. [ Stored in volatile memory ]

FM:INTernal:FUNCtion?

[SOURce:]FM:INTernal:FUNCtion? queries the shape of the modulating waveform. Returns “SIN”, “SQU”, “TRI”, “RAMP”, “NOIS”, or “USER”.

FM:STATe

[SOURce:]FM:STATe OFFON disables or enables Frequency Modulation. To ensure proper operation, you should enable FM after you have set up the other modulation parameters. Only one modulation mode can be enabled at a time. When you enable FM, the previous modulation mode is turned off.

FM:STATe?

[SOURce:]FM:STATe? queries the state of FM. Returns “0” (OFF) or “1” (ON).

FREQuency

[SOURce:]FREQuency <frequency>MINMAX sets the output frequency. MIN selects the lowest frequency allowed for the currently active function. MAX selects the highest frequency allowed for the currently active function. The default frequency is 1 kHz for all functions. Stored in volatile memory.
