FM (Frequency Modulation)
Command Type:
Setting or Query
Setting Syntax:
FM ON I OFF
Query Syntax:
FM?
Examples:
FM ON
FM OFF
Query Response:
FM ON;
FM OFF;
Discussion:
The
on
argument causes the instrument to use the
signal applied to the VCO/FM IN connector to modu­
late the frequency of the main output signal. The
polarity of the external input signal determines the
direction in which the output will deviate in frequency:
a positive-going input signal increases output signal
frequency. The amplitude of the external input signal
determines the percent of frequency change in the
main output signal.
The
off argument terminates frequency modulation.
The query returns the status of the FM command.
