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 =
t
rising edge 2
If the first edge on the display is falling, then
1
Freq =
− t
t
falling edge 2
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
If the first edge on the display is falling, then
Period = t
falling edge 2
Peak-to-Peak Voltage (Vp_p)
The maximum and minimum voltages for the selected source are measured:
− V
Vp_p = V
maximum
where V
and V
