7. Horizontally position the display so that one o f the
positive peaks coincides w ith the center vertical graticule
line (see Figure 12, Point B).
8. Measure the vertical deflection from peak to peak
(see Figure 12, Point A to Point B).

NOTE
i f the amplitude measurement is critical o r i f the
trace is thick (as a result o f hum o r noise on the
signal), a more accurate value can be obtained by
measuring from the top o f a peak to the top o f a
valley. This w ill eliminate trace thickness from the
measurement.
9. Calculate the peak-to-peak voltage, using the fo llo w ­
ing form ula:
vertical VO LTS/DIV probe
Volts (p-p) = deflection x switch x attenuation
(divisions) setting factor
EXAM PLE: The measured peak-to-peak vertical deflec­
tion is 4.6 divisions (see Figure 12) w ith a V O LTS/D IV
switch setting o f 0.5, using a 10X probe.
Substituting the given values:
Volts (p-p) = 4.6 div x 0.5 V/div x 10 = 23 V.
