Sampling Modes Overview
Depending on your timebase, you can choose
Single-shot Sampling
Mode
(below), also known as Real Time mode,
Sequence Sampling
Mode
(on page 56), or
RIS Sampling Mode
(on page 63) mode sampling.
Some instruments also offer
Roll Mode
(on page 64).
Selecting a Sampling Mode
1.
Touch
Timebase → Horizontal Setup...
from the menu bar.
2.
In the
Timebase
dialog, touch a
Sample Mode
button.
3.
If you chose
Sequence Mode
, touch the
Sequence
tab. The
Sequence
dialog is shown. Use the following controls to provide
details for controls such as
Number of Segments
,
Enable Timeout
,
Timeout
(value),
Display Mode
, and
Show Sequence Trigger
Times
.
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
event, while post-trigger delay is the time back to the event. You can
sample the waveform in a range starting well before the trigger event up
to the moment the event occurs.
