Points

In the EMI measurements mode, the Points softkey is only active when the
Measurement CISPR softkey is set to Fast SA Scan. Otherwise EMI mode
automatically sets the points (Default = 401). Learn more, see

Trace Display States (EMI Mode)

For EMI measurements mode this section defines the four trace state
choices for the Fast SA Scan and for CISPR Band Scan, CISPR Zoom Scan,
and APD Statistics choices, it defines the 4th trace display state choices.

The behavior of EMI mode is similar to SA mode. This section describes the
softkeys that have similar, but also different behaviors than SA mode. Learn

How to set the EMI Traces

When the EMI measurement type is set to CISPR Band Scan or CISPR Zoom
Scan Trace 1, Trace 2, Trace 3 have default values assigned. The trace can be
disabled under the Measure 1 (toggle to enable/disable) or the Trace 6
hardkeys or re-assigned to measure a different value on the trace by using the
Trace 6 hardkey (e.g., you can re-assign trace 1 to measure Quasi-peak or EMI
averaging). These detector choices are inactive when the EMI measurement
type is set to, Fast SA Scan or APD Statistics. (i.e., APD statistics does not use
detection; it uses inputs. Refer to
