Page: 6 / 90

Characteristics — Type 543B/RM543B
External (ac low-frequency rejection): Mini­
mum deflection is 0.2 volt from 30 kc to
10 m c, rising to 1 volt at 30 mc with less
than 1 mm of horizontal jitter at a sweep
rate of 20 nsec/cm.
External (dc): Minimum amplitude is 0.2
volt to 10 mc, rising to 1 volt at 30 mc
with less than 1 mm of horizontal jitter
at a sweep rate of 20nsec/cm.
External (automatic): 0.5 v ot 150 cps. Will
trigger from 50 cps to 10 mc with increased
signal.
Accelerating 10 kv.

Area
Focus
6-cm high by 10-cm wide.
Vertical: 2 horizontal lines/mm distinguish­
able over the center 4 cm. 1.5 horizontal
lines/mm distinguishable in the top and
bottom 1 cm.
HORIZONTAL DEFLECTION SYSTEM
The following characteristics apply when the HORIZONTAL
DISPLAY switch is set to the EXT position.
Phosphor
Graticule
Deflection Factor A calibrated deflection of 0.1, 1 or 10
volts/cm with the VARIABLE 10-1 control
set fully clockwise. The VARIABLE 10-1
control provides at least a 10:1 attenua­
tion of the input signal when it is turned

fully counterclockwise.
D c to 500 kc at maximum gain (30%
down).
1 megohm paralleled by approximately
43 pf.
AMPLITUDE CALIBRATOR
Output Voltage 0.2 mvolts to 100 volts peak-to-peak in 18
steps.
Frequency Approximately a 1-kc square wave.
Amplitude
Accuracy Peak-to-peak amplitude accuracy is ±3%
of indicated value. The special output
from the .1 V INTO 50 Ω connector is
accurate to within ±3% of the indicated
value.
Horizontal: 2 time markers./mm distinguish­
able over the middle 8 cm. 1.5 time
markers/mm distinguishable in the first
and tenth cm.
Type 31 phosphor is normally supplied.
Other phosphors are available.
6 X 10 cm with vertical and horizontal
1-cm divisions with 2-mm markings on the
centerlines. Markings for measuring rise­
time have been provided at the 2.5 cm
points above and below the graticule
center line.
