Measurement
This trigger type allows you to leverage parameter measurements as
waveform trigger conditions. A measurement trigger is either the only
trigger or the final trigger in a chain of trigger events including hardware
triggers.
MulitStage
Touching this MultiStage trigger type shows the additional MultiStage
types on the dialog. Select from Cascaded, QualFirst, and Qualified as
follows:
C
ASCADED
The Cascaded trigger allows you to define successive trigger Stages
(referred to as Stage A, B, C, and D) as arm, trigger/arm, trigger/arm,
trigger criteria, respectively.
Q UAL F IRST
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.
