Substituting the given values:
Time Difference = (8. 81-1 . 31) XO . 2f../s .
The time difference is 1.5 microseconds .
TIME DURATION MEASUREMENTS
(BASIC 475A)
Obtain a Delayed Sweep Display. Set the A TIME/DIV
switch to display a single event. Be sure the VAR
TIME/DIV control is in the calibrated detent . For the most
accurate measurement, set the B TIME/DIV switch to the
fastest sweep speed that gives a usable (visible)
inten-
sified zone . Vertically position the display to place the time
measu rement po ints to the center horizontal g raticu Ie line
(see Fig . 26).
Use the DELAY
TIME POSITION dial to move the start
(left-hand edge) of the intensified zone to just touch the
intersection of the signal and the center horizontal
graticule line (see Fig. 26 , Point A) . Note the DELAY TIME
POSITION dial setting .
Fig. 25. Time difference between repetitive pulses.
Use the DELAY TIME POSITION dial to move the start
of the intensified zone to the second time measurement
point (see Fig. 26 , Point B) . Note the DELAY TIME
POSITION dial setting .
