User Manual PXA125
Programming Reference 4-45
FSK:RAMP:TIME?
Response and default
The PXA125 will return the present ramp time value. The returned value will be in standard scientific format
(for example: 10ms would be returned as 10E-3 – positive numbers are unsigned). Default value is 1e-3.
FUNCTion:MODE{FIXed|USER|SEQuence}
Purpose
This command defines the type of waveform that will be available at the output connector.
•
<FIXed> selects standard waveforms
•
<USER> selects arbitrary waveforms
•
<SEQuence> selects sequenced waveforms
Parameter type
Discrete
FUNCTion:MODE?
Response and default
The PXA125 will return FIX, USER, or SEQ depending on the present PXA125 setting. Default value is FIX.
FUNCtion:SHAPe{SINusoid|TRIangle|SQUare|PULSe|RAMP|SINC|EXPonential|
GAUSsian|NOISe|DC}
Purpose
This command defines the shape of waveform that will be available at the output connector. This command
has no affect if present PXA125 setting is USER or SEQ.
•
<SINusoid> selects sine waveform
•
<TRIangle> selects triangular waveform
•
<SQUare> selects square waveform
•
<PULSe> selects pulse waveform
•
<RAMP> selects ramp waveform
•
<SINC> selects sinc waveform
•
<EXPonential> selects exponential waveform
•
<GAUSsian selects gaussian waveform
•
<NOISe> selects random noise waveform
•
<DC> selects dc waveform
Parameter type
Discrete
FUNCtion:SHAPe?
Response and default
The PXA125 will return SIN, TRI, SQU, PULS, RAMP, SINC, EXP, GAUS, NOIS, or DC depending on the
present PXA125 setting. Default value is SIN.
