EMI Measurement Features (Option 361)

The EMI Resolution bandwidth is auto-coupled to keep frequency range
with the selected CISPR band. If the Start or Stop frequencies are
changed, the FieldFox displays a reminder message about the CISPR band
limits.
Example of CISPR messages: "CISPR band StartFreq limited to
30000000" and "CISPR band StopFreq limited to 300000000".
In the CISPR Band Scan measurement, the Span can be changed.
(Exception: CISPR Zoom Scan cannot change the Span.) As the SPAN
changes, the resultant trace point quantity also changes proportionally,
since every FFT spectral sample measured undergoes detection by the
FieldFox firmware and becomes part of the trace (Maximum points ==
75001). Learn more, see
Radio Interference) Control" on page
When selected, CISPR Band and Zoom Scan measurements use one of the
5 CISPR band frequency ranges to set the frequency range (Start and
Stop) on the FieldFox. CISPR Zoom Scan selects a limited fix span (<entire
band range). Learn more, see

Hint!
With any of the EMI measurement settings described in this section, you
can toggle Zero Span and back (i.e., back to your previous measurement)
using the "Zero / Last Span" softkey. Learn more, see
Frequency Range and Frequency Context" on page
For EMI measurements mode this section defines the four trace state
choices for the Fast SA Scan trace display states and for CISPR Band
Scan, CISPR Zoom Scan, and APD Statistics choices, it defines the 4th
trace display state choices. Learn more, see
