Meas. type Symbol Description/result
Delay Delay Time difference between two slopes of the same or different waveforms, measured on the mid-
dle reference level.
A negative result indicates that the slope of the second source comes before the slope of the
first source.
Phase Phs
in °
Phase difference between two waveforms, measured on the middle reference level.
Burst width Bst Duration of one burst, measured on the middle reference level from the first edge to the last
edge.

SHT
Setup and Hold time measurements with positive and/or negative clock edge, measured on the
middle reference level.
Setup/Hold ratio SHR Setup/Hold ratio measurement with positive and/or negative clock edge.
Delay to trigger Dly Trg
in s
Time between the trigger point and a selectable edge, measured on the middle reference level.
If the edge is to the left of the trigger (before trigger), the result is negative.
Slew rate rising SrateRis-
ing
Steepness of the first rising edge, measured between the lower and the upper reference levels.
Slewrt = ΔV / Δt
Slew rate falling SrateFal-
ling
Steepness of the first falling edge, measured between the upper and the lower reference levels.
Slewrt = ΔV / Δt
9.2.4.2 Vertical measurements (amplitude)
The unit of most amplitude measurement results depends on the measured source.
Meas. type Symbol Description/result
High High 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 measurement requires at
least one complete period of the signal.
Low Low 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.
Amplitude Amp Difference between the top level and the base level of the signal. The measurement requires at
least one complete period of the signal.
Max Max Maximum value within the displayed waveform.
Min Min Minimum value within the displayed waveform.
Peak to peak PTP Difference of maximum and minimum values.
Mean Mean Arithmetic average of the complete displayed waveform.
