Delay
Measures the time difference from the selected edge on
Channel 1 and the selected edge on Channel 2 closest to
the trigger reference point at the middle threshold points on
the waveforms
Phase Shift
The calculated phase shift from Channel 1 to Channel 2 (in
degrees)
Amplitude
Measure voltage between Vtop and Vbase of a waveform
Average
Measure average voltage of a waveform
Base
Measure a flat base voltage of a waveform
Maximum
Measure the absolute maximum voltage of a waveform
Minimum
Measure the absolute minimum voltage of a waveform
Overshoot
Measure the overshoot voltage in percentage of a
waveform
Overshoot is a waveform distortion which follows a major
edge transition
Peak to Peak
Measure peak-to-peak voltage of a waveform
(V
Preshoot
Measure the preshoot voltage in percentage of a waveform
Preshoot is a waveform distortion which precedes an edge
transition
VRMS (AC)
The AC VRMS (Root Mean Square Voltage) is a modified
RMS measurement and removes the DC component of the
waveform from the calculation of the RMS voltage
VRMS (DC)
The DC VRMS (Root Mean Square Voltage) measurement is
the classic way of making an RMS voltage measurement
Cycle Mean
Takes VRMS (DC) for one cycle
CREST
Defined as Peak/RMS (Maximum/VRMS (DC))
Top
Measure a flat top voltage of a waveform
Std Deviation
Standard Deviation is an RMS measurement across the full
screen with the DC component removed.
