In single trigger mode,
QualFirst
arms the oscilloscope on the
A event, and then triggers on all subsequent B events.
NOTE
: This button is enabled when using the sequence sampling mode.
It is commonly used in sequence mode for disk drive applications with
the index pulse defined as the A qualifier signal and the servo gate
signal as the B triggering events.

A-B
In single trigger mode,
Qualify A-B
arms the oscilloscope on
the A event, and then triggers on the B event. If the
oscilloscope is in Normal trigger mode, it automatically resets
after the B event. Arm trigger events can be set for

State
The
State
trigger is a level-qualified trigger which requires
that the qualifying signal remain above or below a specified
voltage level for a trigger to occur. For State trigger, you
specify the time or number of events after the signal has gone above or
below the voltage level when you want the trigger to occur.
Serial Trigger
A 14.1 Gb/s Serial Trigger is optionally available for LabMaster
10 Zi. This trigger is installed in a 10-xxZi acquisition module
and is permanently connected internally for use on Channel 4 only. The
10-xxZi Acquisition Module that contains this trigger should be the first
acquisition module (i.e. Channels 1 – 4) in any multi-acquisition module
system.
This trigger option provides capability for Non-Return to Zero (NRZ) 80-
bit pattern and 8b/10b symbol triggering. Additional capabilities are
planned for the future.
