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.
PicoScope 2203, 2204, 2204A, 2205 and 2205A only
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. For
allowable values see ps2000.h.
stopFrequency: the frequency at which the sweep should reverse direction or
return to the start frequency
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
sweepType: specifies whether the frequency should sweep from startFrequency
to stopFrequency, or in the opposite direction, or repeatedly reverse direction.
Use one of these values of the enumerated type enPS2000SweepType:
PS2000_UP
PS2000_DOWN
PS2000_UPDOWN
PS2000_DOWNUP
sweeps: the number of times to sweep the frequency
0: if one of the parameters is out of range
non-zero: if successful
