Sampling Modes
Depending on your timebase, the following sampling modes are available:
WaveStream Mode - This fast viewing mode provides
brightness-graded intensity with a decay time similar to the
action of phosphor on an analog screen. WaveStream mode
operates at up to 10 GS/s with an update rate up to 22,000
waveforms/second for better capture of higher frequency
abnormal events.
Real Time Mode - A single-shot (real time) acquisition is a
series of digitized voltage values sampled on the input signal
at a uniform rate.
Sequence Mode - In sequence mode, the complete waveform
consists of a number of fixed-size segments acquired in single-
shot mode
Roll Mode - This mode is invoked automatically for slow
acquisitions when the time per division is 100 ms/div or
greater. Roll mode samples at 5 MS/s (depending on memory
availability).
RIS Mode - Random Interleaved Sampling is an acquisition
technique that allows effective sampling rates higher than the
maximum single-shot sampling rate. It is used on repetitive
waveforms with a stable trigger
Single-shot Sampling Mode
Basic Capture Technique
A single-shot acquisition is a series of digitized voltage values sampled on
the input signal at a uniform rate. It is also a series of measured data values
associated with a single trigger event. The acquisition is typically stopped a
defined number of samples after this event occurs: a number determined
by the selected trigger delay and measured by the timebase. The
waveform's horizontal position (and waveform display in general) is
determined using the trigger event as the definition of time zero.
You can choose either a pre- or post-trigger delay. Pre-trigger delay is the
time from the left-hand edge of the display grid forward to the trigger
