Depending on the timebase, any of three sampling modes
can be chosen: Single-Shot, Random Interleaved Sampling
(RIS) or Roll Mode. Furthermore, for timebases suitable for
either Single-Shot or Roll Mode, the acquisition memory can
be subdivided into user-defined segments to give Sequence
Mode. Channels can also be combined to boost sample rate
and record length.
6LQJOH6KRW Single-Shot is the digital oscilloscope's basic acquisition
technique and other timebase modes make use it.
An acquired waveform consists of a series of measured voltage
values sampled at a uniform rate on the input signal. The
acquisition, a single series of measured data values associated
with one trigger event, is typically stopped at a fixed time after the
arrival of the event, this being dete|
