10. Set the A SEC/DIV switch to a position that displays 12. Calculate the instantaneous voltage, using the follow-
several cycles o f the signal. ing formula:
11. Measure the divisions of vertical deflection between
the reference line and the desired point on the waveform
at which the dc level is to be determined (see Figure 14).

The measured vertical deflection from the
reference line is 4.6 divisions (see Figure 14), the wave­
form is above the reference line, the VO LTS/DIV switch
is set to 2, and a 10X attenuator probe is being used.
Substituting the given values:
Instantaneous Voltage = 4.6 div x (+1) x 2 V/div
x 10 = 92 V.
Algebraic Addition
With the VER TICAL MODE switch in the ADD posi­
tion, the waveform displayed is the algebraic sum o f the
signals applied to the Channel 1 and Channel 2 inputs
