Set the Sampling Mode
Background
The GDS-3000 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.
Panel Operation
1. Press the Acquire key.
Acquire
2. Press the ET/sin(x)/x key on the
bottom menu to toggle between
equivalent time sampling (ET) and
sin(x)/x interpolation.
The sampling rate will be shown on the bottom right-
hand corner
