Measurement Algorithms
Frequency (Freq)
The frequency of the first complete cycle displayed is measured using the
50% levels.
If the first edge on the display is rising, then
Freq =
1
t
rising edge 2
−
t
rising edge 1
.
If the first edge on the display is falling, then
Freq =
1
t
falling edge 2
−
t
falling edge 1
.
Period
The period is measured at the 50% voltage level of the waveform.
If the first edge on the display is rising, then
Period = t
rising edge 2
−
t
rising edge 1
.
If the first edge on the display is falling, then
Period = t
falling edge 2
−
t
falling edge 1
.
Peak-to-Peak Voltage (Vp_p)
The maximum and minimum voltages for the selected source are measured:
Vp_p = V
maximum
−
V
minimum
,
where V
maximum
and V
minimum
are the maximum and minimum voltages
present on the selected source.
