Rise(Fall) Time Measurement - Goldstar OS-7020 Service Manual

6-4 Rise(Fall) time measurement
1. Display the pulse waveform vertically and horizontally
in the same manner as for the pulsewidth measurement
procedure.
2. Turn the horizontal POSITION control in order to set the
upper
10%
point of the waveform on the vertical center
line of the graticule. Read the distance Tl between the
vertic· 1 center line and the point at which the rising
(falling) edge crosses the horizontal center line.
3. Shift and set the lower
10%
point of the waveform to the
vertical center line of the graticule as shown
by
the
dotted line in Fig 6-5. Read the distance T2 between
the vertical center line and the point at which the rising
(or falling) edge crosses the horizontal center line.
4. Calculate the rise(or fall) time by substituting the sum
of Tl and T2
