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
startDeltaPhase: the initial value added to the phase counter as the generator begins to
step through the waveform buffer
stopDeltaPhase: the final value added to the phase counter before the generator restarts
or reverses the sweep
deltaPhaseIncrement: the amount added to the delta phase value every time the
dwellCount period expires. This determines the amount by which the generator sweeps the
output frequency in each dwell period.
dwellCount: the time, in multiples of ddsPeriod, between successive additions of
deltaPhaseIncrement to the delta phase counter. This determines the rate at which the
generator sweeps the output frequency.
arbitraryWaveform: a pointer to a buffer that holds the waveform pattern as a set of
samples equally spaced in time
arbitraryWaveformSize: the size of the arbitrary waveform buffer
sweepType: determines whether the startDeltaPhase is swept up to the
stopDeltaPhase, or down to it, or repeatedly swept up and down. Use one of the following
values:
UP
DOWN
UPDOWN
DOWNUP
sweeps: the number of times to sweep the frequency after a trigger event, according to
sweepType.
