2.4.1.8 EMI Average
Selects EMI averaging detection. EMI Average detection displays the average value of
amplitude envelope. It is defined for EMI measurements by the CISPR standard and uses
the VBW filter as a low pass filter, the output of which is sampled during the bucket
interval. This functionality is quite different from the Average detector.

Dependencies/
Couplings: Whenever the EMI Average detector is selected, the resolution bandwidths
available will be the CISPR set listed in Table 2-2, “CISPR Bandwidths
with RBW Set to Auto,” and Table 2-3, “CISPR Bandwidths with RBW Set
to Manual,” on page 86.
The Video BW is restricted to 1 Hz while VBW is is set to Auto.
History: Firmware revisions A.06.00
Remote Command:
See “Detector” on page 79.

2.4.1.9 EMI Peak
Selects peak detection. This is the same detection as the regular Peak detector. The
difference is the Auto resolution bandwidths that are available as described in Table 2-2,
“CISPR Bandwidths with RBW Set to Auto,” and Table 2-3, “CISPR Bandwidths with
RBW Set to Manual,” on page 86.

analyzer is in
Manual:FFT mode.
