1GSa/s & Single Shot
Background By using a very fast sampling rate combined with
single shot trigger mode, you can accurately
reconstruct weak signals which are buried in
larger waveform. Here you can observe a tiny
pulse sitting on top of PECL, 3.3V DC signal.

This demo uses a BNC to BNC cable instead of probe.
CH1 Scale 25ns/div, 50mV/div (1GSa/s)
