User Manual PXA125

Programming Reference 4-41

Parameter range

1e-3 to 10e6 in units of samples per second

FM:FREQuency:RASTer?

Response and default
The PXA125 will return the present modulating waveform sample clock frequency value. The returned value
will be in standard scientific format (for example: 1KHz would be returned as 1E3 – positive numbers are
unsigned). Default value is 1e6.

FM:TRIGger:MODE{CONTinuous|TRIGered|GATEd}

Purpose
This command will select one of the FM modes.

CONTinuous will select continuous modulation

TRIGered will select triggered modulation

GATEd will select gated modulation

Parameter type

Discrete

FM:TRIGger:MODE?

Response and default
The PXA125 will return CONT, TRIG, or GATE depending on its present setting. Default is CONT.

FM:TRIGger:SLOPe{POSitive|NEGative}

Purpose
This command will select slope sensitivity for the FM trigger input.

POSitive will select rising edge

NEGative will select falling edge

Parameter type

Discrete

FM:TRIGger:SLOPe?

Response and default
The PXA125 will return POS, or NEG depending on its present setting. Default is POS.

FREQuency{|MINimum|MAXimum}

Purpose
This command modifies the frequency of the standard waveform in units of hertz (Hz). It has no affect on
arbitrary waveforms.

sets the waveform frequency

sets the waveform frequency to its lowest value

sets the waveform frequency to its highest value
