Set the Sampling Mode
Background
The GDS-2000A has two types of sampling modes:
ET (Equivalent Time) and Sin(x)/x interpolation.
Equivalent time sampling is able to achieve a
sample rate of 100GSa/s when sampling periodic
waveforms. Sin(x)/x interpolation uses a sinc
interpolation formula to reconstruct a continuous
signal between sampled points.

Sin(x)/x
One sample of data is used to
reconstruct a single waveform.
Sin(x)/x sampling should be used
when the time base is relatively
slow or if single shot events need to
be captured.

time sampling
time sampling
Sampled data is accumulated a
number of times to reconstruct a
single waveform. This increases the
sampling rate, but can only be used
for repetitive signals. This mode is
usually used when the time base is
too fast for real-time sampling.
