the 10% and 90% points on the leading edge o f the wave­
form. Fall 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.
4. Vertically position the trace so that the zero refer­
ence o f the waveform touches the 0% graticule line and the
top o f the waveform touches the 100% graticule line (see
Figure 25).
5. Set the A SEC/DIV switch for a single-waveform
display, w ith the rise time spread horizontally as much as
possible. Ensure that the A SEC/DIV TIME (PULL) VAR
control is in the calibrated detent.
