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 =
If the first edge on the display is falling, then
Freq =
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 Vmaximum and Vminimum are the maximum and minimum
voltages present on the selected source.
