9. Record the B D ELAY TIME POSITION control dial
setting.
10. Determine the time duration using the follow ing
form ula:
Time /second first \ /A S E C /D IV \
Difference = { dial - dial j I switch ]
(Duration) \ reading reading / \ setting /
EXAMPLE: With the A SEC/DIV switch set to 2 ms,
the first B D ELAY TIME POSITION dial setting (Point
A) is 1.20 and the second B D ELAY TIME POSITION
dial setting (Point B) is 9.53 (see Figure 24).
Substituting the given values:
Time Duration = (9.53 — 1.20) (2 ms) = 16.66 ms
Rise Time
Rise-time measurements use the same methods as time
duration, except that the measurements are made between
the 10% and 90% points on the leading edge o f the wave­
form . Fail time is measured between the 90% and 10%
points on the trailing edge o f the waveform.

1. Preset instrument controls and obtain a Normal
Sweep Display.
2. Apply the signal to either vertical-channel input
connector and set the VE R TIC A L MODE switch to display
the channel used.
3. Set the appropriate VO LTS/DIV switch and VAR
control fo r an exact 5-division display.
