Parameters
Vertical
Max
Highest value in input waveform
Min
Lowest value in input waveform
Pk-Pk
Difference between maximum and minimum data values
Ampl
Difference between top and base in a bimodal signal, or between max
and min in an unimodal signal
Top
Value of most probable higher state in a bimodal waveform
Base
Value of most probable lower state in a bimodal waveform
Mean
Average of all data values
Cmean
Average of data values in the first cycle
Stdev
Standard deviation of all data values
Cstd
Standard deviation of all data values in the first cycle
VRMS
Root mean square of all data values
Crms
Root mean square of all data values in the first cycle
FOV
Overshoot after a falling edge;(base -min)/Amplitude
FPRE
Overshoot before a falling edge;(max -top)/Amplitude
ROV
Overshoot after a rising edge;(max -top)/Amplitude
RPRE
Overshoot before a rising edge;(base -min)/Amplitude
Level@X
the voltage value of the trigger point
Horizontal
Period
Time between the middle threshold points of two consecutive, like-
polarity edges
Freq
Reciprocal of period
+Wid
Width measured at 50% level and positive slope
-Wid
Width measured at 50% level and negative slope
Rise Time
Duration of rising edge from 10 -90%
Fall Time
Duration of falling edge from 90 -10%
Bwid
Time from the first rising edge to the last falling edge, or the first falling
edge to the last rising edge at the 50% crossing
+Dut
Time difference between the 50% threshold of a rising edge to the 50%
threshold of the next falling edge of the pulse
-Dut
Time difference between the 50% threshold of a falling edge to the 50%
threshold of the next rising edge of the pulse
Delay
Time from the trigger to the first transition at the 50% crossing
Time@Level
Time from the trigger to each rising edge at the 50% crossing.
When Statistics is Off, it shows the time from the trigger to the last rising
edge at the 50% crossing.
When Statistics is On, it shows the Current, Mean, Min, Max, Standard
Deviation of time from the trigger to each rising edge at the 50% crossing
in multiple frames (number = Count).
Delay
Phase
Phase difference between two edges
FRR
Time from the first rising edge of channel A to the following first rising
edge of channel B
FRF
Time from the first rising edge of channel A to the following first falling
