Meas. type Symbol Description Graphic / formula
Delay Dly
in s
Time difference between two slopes of the same or different
waveforms, measured on the middle reference level. The
settings of slope selection are described in Chapter 8.2.4,
"Delay setup", on page 157.
A negative result indicates that the slope of the second
source comes before the slope of the first source.

8.2.2.2 Vertical measurements (Amplitude)
The unit of most amplitude measurement results depends on the measured source.
Meas. type Symbol Description Graphic / formula
Amplitude VAmp Difference between the top level and the base level of the
signal. The measurement requires at least one complete
period of the signal.

Amplitude
Top Level Vtop High level of the displayed waveform - the upper maximum
of the sample distribution, or the mean value of the high
level of a square wave without overshoot. The measure-
ment requires at least one complete period of the signal.
Top
Base Level Vbase Low level of the displayed waveform - the lower maximum
of the sample distribution, or the mean value of the low level
of a square wave without overshoot. The measurement
requires at least one complete period of the signal.
