Additional Frequency Modulation Commands - Agilent Technologies 6813B User Manual

Additional Frequency Modulation Commands

The following SCPI commands are used to program the output frequency of the ac source. These
commands apply only to the Main Output of the ac source and do not affect the measurement capability
of the unit. These commands are only provided with the Agilent Dual Power Analyzer Option 020/022.
FM
Turns off or on frequency modulation of the Main Output. Frequency modulation operates only if
FREQuency:MODE is set to FIXed.
Command Syntax [SOURce:]FM[:STATe] <bool>
Parameters 0 | 1 | OFF | ON
*RST Value OFF
Examples FM 1
Query Syntax [SOURce:]FM[:STATe]?
Returned Parameters 0 | 1
Related Commands FM:DEV FM:FREQ
FM:DEViation
Sets the peak frequency deviation of the output frequency modulation in Hertz. The frequency deviation
must be less than the programmed output frequency by at least 0.001 Hz. For example, if the output
frequency is set to 60 Hz, and you program a deviation of 10 Hz, the output frequency will modulate
between 50 and 70 Hz at a rate determined by the FM:FREQuency command.
