Oscilloscope Reference Measurement algorithms
Negative over
shoot
Amplitude (voltage) measurement.
Note that this value should never be negative (unless High or Low are set out-of-range).
Negative width
Timing me
asurement. The distance (time) between MidRef (default = 50%) amplitude points of a negative
pulse.
If MCros
s1Polarity =–
then
NegativeWidth = (MCross2–MCross1)
else
NegativeWidth = (MCross3–MCross2)
Waveform[Start]
Optical power
See Mean dBm (see page 733).
Peak to peak
Amplitude measurement. The absolute difference between the maximum and minimum amplitude.
PeaktoPeak = Max – Min
Period
Timing measurement. Time taken for one complete signal cycle. The reciprocal of frequency. Measured
in seconds.
Period = MCross3 – MCross1
