SECTION 1
CHARACTERISTICS
Introduction
The Type 543B Oscilloscope is a versatile laboratory
instrument designed for use with all Tektronix lettered- or
1 -series plug-in units.

SWEEP GENERATOR
Sweep Rates
0.1 µsec/cm to 5 sec/cm in 24 calibrated
steps. Displayed sweep-rate accuracy is
±3%. An uncalibraied variable sweep­
rate control permits the sweep to be
slowed to at least 0.4 of the indicated
rate.
Sweep
Magnification Any sweep rate can be increased 2, 5, 10,
20, 50 or 100 times by expanding the
center portion of the display horizontally.
Sweep-rate accuracy is within ~5% in the
magnified positions until the sweep rate
exceeds 0.02 µsec/cm.
Internal, external, and fine.
Automatic, dc, ac, and ac low-frequency
rejection.
Internal (ac): Minimum deflection is 2 mm,
from 150 cps to 10 mc, rising to 1 cm at
30 me with less than 1 mm of horizontal
jitter at a sweep rate of 20 nsec/cm.
Internal (de): Minimum deflection is 6 mm
to 10 mc.
Internal (ac low-frequency rejection): Mini­
mum deflection is 2 mm, from 30 kc to
10 mc, rising to 1 cm at 30 mc with less
than 1 mm of horizontal jitter at a sweep
rate of 20 nsec/cm.
Internal (automatic): 5 mm deflection at
150 cps. Will trigger from 50 cps to 10 mc
with increased deflection.
External (ac): Minimum amplitude is 0.2
volt, from 150 cps to 10 mc, rising to 1
volt at 30 mc with less thon 1 mm of hori­
zontal jitter at a sweep rate of 20 nsec/cm.
