Parameters
FM:INTernal:FREQuency?
[SOURce:]FM:INTernal:FREQuency? [MIN|MAX] queries the modulating
frequency. Returns a value in hertz.
FM:INTernal:FUNCtion
[SOURce:]FM:INTernal:FUNCtion SIN|SQU|TRI|RAMP |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 OFF|ON 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>|MIN|MAX 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.
