Teledyne LeCroy PXA125 - Manual (Page 159)

User Manual PXA125
Programming Reference 4-41
Parameter range
<FM_sclk> 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{<freq>|MINimum|MAXimum}
Purpose
This command modifies the frequency of the standard waveform in units of hertz (Hz). It has no affect on
arbitrary waveforms.
•
<freq> sets the waveform frequency
•
<MINimum> sets the waveform frequency to its lowest value
•
<MAXimum> sets the waveform frequency to its highest value
