Conducted Emissions Measurement Examples
Making Conducted Emission Measurements
Measuring the Quasi-peak and average values of the signals
Measurement tip
If the signals you are looking at are in the lower frequency range of the conducted
band, 2 MHz or lower, you can reduce the stop frequency to get a closer look. Note
that there are fewer points to view. You can add more data points using the scan
table. The default setting in the scan table is two data points per BW or 4.5 kHz per
point in this case since the resolution bandwidth is 9 kHz. To get more data points,
change the points per bandwidth to four points.
Step Action Notes
1 Perform a Re-measure on
all signals in the list
a. Press Meas Setup, Scan.
Sequence, (Re)measure,
(Re)measure, All Signals,
Sweep/Control, Start.
2 Review the measurement results The delta to Limit Line values
should all be negative. If some
of the measurements are
positive, there is a problem
with conducted emissions from
the DUT.
