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. This is 100% pre-trigger, and it allows you to
see the waveform leading up to the point at which the trigger condition
was met and the trigger occurred. (The instrument offers up to the
maximum record length of points of pre-trigger information.) Post-trigger
delay, on the other hand, allows you to sample the waveform starting at
the equivalent of 10,000 divisions after the event occurred.
On fast timebase settings, the maximum single-shot sampling rate is used.
But for slower timebases, the sampling rate is decreased and the number
of data samples maintained.
The relationship between sample rate, memory, and time can be simply
defined as:
Capture Interval = 1 /Sample Rate X Memory
and
Capture Interval /10 = Time Per Division
Sequence Sampling Mode
– Working with
Segments
Using Sequence Mode, you can store up to 15,000 triggered events as
segments into the oscilloscope's memory. This is ideal when capturing
many fast pulses in quick succession or when capturing few events
separated by long time periods. The instrument can capture complicated
sequences of events over large time intervals in fine detail, while ignoring
the uninteresting periods between the events. You can also make time
measurements between events on selected segments using the full
precision of the acquisition timebase.
Sequence mode offers a number of unique capabilities:

You can acquire up to four channels simultaneously.

You can minimize dead time between trigger events for consecutive
segments.

You can view time stamps for acquisitions.

You can zoom segments or used them as input to math functions.
