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.
