Unique Trigger Captures Data From Cyclic Processes
Many measurement applications
require the acquisition of bursts
of data following an independ-
ent, index synchronization pulse.
This is true for sector data stored
on a disk drive, mechanical
analysis of rotating machines and
engines, and read/write opera-
tions to multiplexed memory. In
each case, the underlying opera-
tion involves a cyclic process
with synchronization sources as-
sociated with each individual
event within the cycle, as well as
a once per cycle index pulse.
A good example of this type of
process is the organization of
data sectors on a disk drive. In
