Measure 1 Hardkey – EMI 'Convenience' Softkeys
IMPORTANT!
When you press the Measure 1 hardkey a softkey menu is displayed and
has, as a convenience, fixed values for Trace 1 (PosPeak T1), Trace 2
(QuasiPeak T2), Trace 3 (EMIAverage T3) assigned. While the softkey
labels cannot be re-assigned, the trace values can be changed manually
under the Traces 6 hardkey using the Detector softkey. Learn more, refer
to
— Press Measure 1 then choose:

Trace Averaging

Within EMI mode, the detectors provide the critical necessary averaging (i.e.,
EMI Average and Quasi Peak), but similar to SA mode, if needed, you can
perform Trace Averaging. Refer to
Count" on page 214
233–Mixed Analyzers)."

Alignments

EMI measurements mode uses amplitude alignment and channel equalization.
Learn more, refer to the SA chapter's
information on all alignments.

— QuasiPeak T2 – Enable/Disable trace 2 to display quasi-Peak data
that weighs each component based on its repetition rate: the faster
repetition rate, the higher the weight given to that component
(Default = on). Q annotation is displayed. This softkey is inactive,

— EMIAverage T3 – Enable/Disable trace 3 to display EMI average data
displays the average amplitude of each signal component across its
period (Default = on). A annotation is displayed. This softkey is
