Up sampling (2.8.5.2.)
Description Specifies the number of consecutive echoes that must appear above the echo
currently selected, before the measurement is accepted as valid.
Values Range: 1 to 50
Factory setting 5

7.2.7.6 Echo quality (2.8.6.)
Confidence (2.8.6.1.)
Description Indicates echo reliability: higher values represent better echo quality. The display
shows the echo confidence of the last measurement. Echo threshold (2.8.4.3.)
(Page 112) defines the minimum criterion for echo confidence.

Echo strength (2.8.6.2.)
Description Displays the absolute strength (in dB above 1 μ V rms) of the echo selected as
the measurement echo.
Values (view only) –20 to 99
Noise average (2.8.6.3.)

Noise level is a combination of transient noise and receiving circuitry. After a measurement,
the values from the previous noise shot will be displayed.
