This function sets up the signal generator to produce a signal from a list of built-in

waveforms. If different start and stop frequencies are specified, the device will sweep

either up, down or up and down.

Applicability

All modes

Arguments

handle, the handle of the required device

offsetVoltage, the voltage offset, in microvolts, to be applied to the waveform

pkToPk, the peak-to-peak voltage, in microvolts, of the waveform signal

waveType, the type of waveform to be generated.

PS6000_SINE

sine wave

PS6000_SQUARE

square wave

PS6000_TRIANGLE

triangle wave

PS6000_RAMP_UP

rising sawtooth

PS6000_RAMP_DOWN

falling sawtooth

PS6000_SINC

sin (x)/x

PS6000_GAUSSIAN

Gaussian

PS6000_HALF_SINE

half (full-wave rectified) sine

PS6000_DC_VOLTAGE

DC voltage

PS6000_WHITE_NOISE

white noise

startFrequency, the frequency that the signal generator will initially produce. For

allowable values see PS6000_SINE_MAX_FREQUENCY and related values.

stopFrequency, the frequency at which the sweep reverses direction or returns to

the initial frequency

increment, the amount of frequency increase or decrease in sweep mode

dwellTime, the time for which the sweep stays at each frequency, in seconds
