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

— 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

when APD Statics is ON and or CISPR Band E is selected.
— 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
inactive, when APD Statics is ON.
