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 oscilloscope will

sweep either up, down or up and down.

Applicability

PicoScope 4226, 4227 and 4262 only

Arguments

handle, the handle of the required oscilloscope

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 by the

oscilloscope. See the table below.

startFrequency, the frequency at which the signal generator

should begin. Range: MIN_SIG_GEN_FREQ to

MAX_SIG_GEN_FREQ.

stopFrequency, the frequency at which the sweep should

reverse direction or return to the start frequency. Range:

MIN_SIG_GEN_FREQ to MAX_SIG_GEN_FREQ.

increment, the amount by which the frequency rises or falls

every dwellTime seconds in sweep mode

dwellTime, the time in seconds between frequency changes in

sweep mode
