end point
LAP-F1 will not trigger immediately (i.e. when the H/L event being
looked for changes state) upon finding an event that satisfies the
pulse-width condition, but wait until the Pulse-width Max number
of samples is reached and then trigger. The Pulse-width Max is
counted from the beginning of the H/L event in question.
Trigger Levels
Trigger Level
There are 256 Trigger Levels. When the conditions of Level 1 are
satisfied the LAP-F1 looks for an event that satisfies the conditions
of Level 2. When an event satisfying the last active trigger level is
found the LAP-F1 triggers. Note that Level X must be activated
before Level X-1 can be activated.
Pre-Fill Data
The Trigger Position combined with the Sample Depth determines
how many bits of pre-trigger data should be stored. The Pre-Fill
Data determines the ZP-Logic’s behavior if the trigger event occurs
before the pre-trigger data requirement has been fulfilled. If
unchecked (default option) the LAP-F1 will override the Trigger
Position/Sample Depth requirement and start storing data when
the trigger event occurs. If checked, triggering will be postponed
until the pre-trigger data requirement has been fulfilled.
All Levels Inactive
Disable all trigger levels.
Default All Levels
Set all trigger levels to default.
Trigger Count
Trigger on the Xth event that satisfies the trigger conditions; at the
default value of 1 the LAP-F1 will trigger on the first event.
Trigger Mark
Place a vertical bar on all samples that meet the trigger conditions.
By default, only one trigger bar is shown (the T-bar), but there can
be up to 256 trigger bars. These are numbered T0, T1, T2 etc.
(Trigger Marks are sometimes referred to as Cursors or Auxiliary
Cursors).
