AMPLITUDE MEASUREMENTS

P eak-to-P eak Voltage

This procedure may be used to make peak-to-peak voltage
measurements between any two points on the waveform.
1. Apply the signal to either the CHI or the CH2 input connec­
tor and set the VERTICAL MODE selector to display the chan­
nel used.
2. Set the appropriate VOLTS/DIV control to display about 5
divisions of the waveform and ensure that the VOLTS/DIV
variable control is in the CAL detent.
3. Adjust the TRIGGER LEVEL control to obtain a stable display.
4. Rotate the SEC/DIV control to a setting that displays at least
one cycle of the waveform.
5. Vertically position the display so that the negative peak of
the waveform coincides with one of the horizontal graticule
lines (see Figure 3 -1 , Point A ).
6. Horizontally position the display so that one of the positive
peaks coincides with the center vertical graticule line (Figure
3 -1 , Point B ).
7. Measure the divisions of vertical deflection from p e a k-to -
peak (Figure 3 -1 , Point A to Point B).
