Agilent Technologies E4406A manual Troubleshooting Hints, differing values for the maximum point

	Making the Waveform (Time Domain) Measurement
	In the Waveform measurement, the Mean Pwr (Entire Trace) value
NOTE
	plus the Pk-to-Meanvalue will sum to equal the current Max Pt. value
	as shown in the data window below the RF Envelope display. If you do a
	marker peak search (Search) with averaging turned off, the marker will
	find the same maximum point. However, if you turn averaging on, the
	Pk-to-Meanvalue will use the highest peak found for any acquisition
	during averaging, while the marker peak will look for the peak of the
	display, which is the result of n-averages. This will usually result in
	differing values for the maximum point.
	Troubleshooting Hints
	Changes made to advanced waveform settings can inadvertently result
	in measurements that are invalid and cause error messages to appear.
	Care needs to be taken when using advanced features, as some settings
	may incorrectly appear to provide a valid result. Press Meas Setup, More,
	Restore Meas Defaults to return measurement settings to a known state,
	then vary settings only as necessary.
