TRIGGER DELAY .
Change the trigger delay and notice that when the trigger delay is greater than the pulse
width, the trace level decreases to the noise o or b ecause the measurement is being made
after the pulse has turned O.

DUTY CYCLE . Change the the duty cycle limit. This changes the maximum duty
cycle percent allowed by the internal measurement timing logic. Notice that combinations
of long pulse width and low p ercentduty cycle will increase the measurement time for each
data point.

Cycle
In
the
F
requency
domain:
Without a
veraging, pulse
width and dut
y cycle settings resulting in less than
about 30 milliseconds PRP will not c
hange the actual system PRP
.
With a
veraging, pulse width
and duty cycle settings resulting in less than
about 1 millisecond PRP will not change the actual system PRP.
To learn more ab out control of these values, refer to the General Timing
