OD1402 - Lesson 1/Learning Event 1
Control of the graticule lines' brightness is provided by the GRAT
ILLUM control. Figure 10 shows the graticule layout and defines
the various measurements lines.
CALCULATING VOLTAGE MEASUREMENTS
AC Voltages
We calculate AC voltages in this manner: the number of centimeters
(cm) or grid squares of vertical deflection of signal amplitude,
times the setting of the VOLTS/DIV switch, equals the peaktopeak
voltage of the input signal.
Signal Amplitude (cm) x VOLTS/DIV Switch = PeaktoPeak
Setting
Voltage
Using the formula, you should be able to calculate the peaktopeak
voltage of the displayed waveform (figure 11, below).
Your answer should be 1 volt. 2(cm) x .5 volts = 1 volt peakto
peak.
