trigger signal.
Single Sweep—Sweep Generator produces
only one sweep when triggered. Fur
ther sweeps are locked out until R E -
SET button is pressed.
Calibrated Sweep Rates

23 steps in a 1-2-5 sequence.
Magnifier
Direct-reading, six position, push to turn
switch w ith up to 50 times maximum
magnification. Extends the fastest sweep
rate to 20 nanoseconds/division.
