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

FM:STATE ON

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.

Command Syntax

[SOURce:]FM:DEViation <NRf>

Parameters

0 to 1000 Hz

*RST Value

0

Unit

Hz (Hertz)

Examples

FM:DEV 10

Query Syntax

[SOURce:]FM:DEViation?

Returned Parameters

<NR3>

Related Commands

FM FM:FREQ

FM:FREQuency

Sets the modulating frequency of the output frequency modulation in Hertz.

Command Syntax

[SOURce:]FM:FREQuency <NRf>

Parameters

0.001 to 1000 Hz

*RST Value

0.1

Unit

Hz (Hertz)

Examples

FM:FREQ 1

Query Syntax

[SOURce:]FM:FREQuency?

Returned Parameters
