2. Apply the signal to either vertical-channel input
connector and set the VERTICAL MODE switch to display
the channel used.
3. Adjust the A TRIGGER LEVEL control to obtain
a stable display.
4. Set the A SEC/DIV switch to display one complete
period of the waveform. Ensure that the TIME (PULL)
VAR control is in the calibrated detent.
5. Position the display to place the time-measurement
points on the center horizontal graticule line (see Fig-
ure 17).
6. Measure the horizontal distance between the time-
7. Calculate time duration, using the following formula:
horizontal A SEC/DIV
Time _ (divisions) setting
EXAMPLE: The distance between the time-measurement
points is 8 divisions (see Figure 17), and the A SEC/DIV
switch is set to 2 ms. A magnification factor of 1 is used.
Substituting the given values:
Time Duration = 8.3 div x 2 ms/div = 16.6 ms
