In manufacturing, the goal is
to minimize test time, so the
combination of precision DCV
and peak measurements can
significantly reduce test time
compared to making individual
DCV and ACV measurements
or digitizing and processing the
signal. The additional benefit
is obtaining the peak-to-peak
information which can better
indicate the quality of the
power supply’s output signal.
Precision measurements
with level triggering
The following waveform (Figure 2)
represents the current drain of
a battery during an operation
in a hand-held device. The goal
is to measure the average DC
value of the pulse, but only
during the duration of the pulse.
This pulse has no associated
5-V logic signal event that can be
used as a synchronous external
trigger. At first, it would seem
that capturing the asynchronous
event with a large number of
high-speed measurements –
followed by processing the
waveform in a computer to
come up with the result –
would be the only solution.
Figure 2. Peak detect occurs at 20-µs intervals over the duration of the measurement aperture
This is a relatively simple mea-
surement to make for a DMM
that has analog level triggering.
No external TTL-pulse is needed
to start the measurement. The
34411A is set to trigger at some
point on the rising edge of the
pulse (a percent of range). A
trigger delay can be used to
make sure the measurement
starts on the “flat” portion
of the pulse, and the A-to-D
aperture is set to a value that
maximizes the precision of the
measurement without exceeding

the duration of the pulse width.
In the example, a 100-µs delay
from the level trigger will place
the beginning of the measure-
ment past the rising edge.
Using a 1-ms aperture, the
34411A can make a 6
measurement. In addition, any
DC measurement allows the
use of the peak measurement
function to capture the peak-
to-peak content, as shown in
the previous example.
