SPECIFICATIONS
The Tektronix Type 502 Oscilloscope provides linear dual-beam
displays with a wide range of sweep rates combined with high in
put sensitivity. In addition, the Type 502 may be used to provide
dual-beam X-Y displays at medium sensitivities, and single-beam
X-Y displays at high sensitivities. Vertical amplifiers for both
beams may be operated with single-ended inputs for conventional
operation, or with differential inputs for cancellation of common
mode signals. The wide range of operational modes available,
make the Type 502 adaptable to a great many industrial and
scientific applications.
VERTICAL- DEFLECTION SYSTEM
Characteristics at each input terminal
Direct connection— 1 megohm paralleled by
47 /a/aT With P510A probe— 10 megohms
paralleled by 14^/Af.
Deflection factors
Sixteen calibrated deflection factors from 200
fxv/cm to 20v/cm accurate within 3%.
Frequency response
Frequency response characteristics of the Type
502 vary with settings of the SENSITIVITY con-
Typical readings are as follows: X
200 /Av/cm
100 kc W-
5 mv/cm
200 kc
50 mv/cm
400 kc
.2 v/cm
1 me . X
Differential input rejection ratio
The rejection ratios specified below apply if
the signal voltage at the Input connector
does not exceed specified limits. The signal
limits for dc-coupling are ± 2 volts with respect
to ground for settings of the SENSITIVITY con
trol from 200/Av/cm to .2v/cm , =±=20 volts
with respect to ground for settings from
.5v/cm to 2v/cm , and ± 2 0 0 volts with re
spect to ground for settings from 5v/cm to 20
v/cm. For ac coupling, the signal limits are 2
volts peak-to-peak from 200/xv/cm to .2 v/cm,
20 volts peak-to-peak from .5 v/cm to 2 v/cm,
and 200 volts peak-to-peak from 5 v/cm to 20
v/cm. From 200/xv/cm to 1 mv/cm, the rejec
tion ratio is approximately 1000-to-l, decreas
ing to 100-to-1 at 0.2 v/cm, and to 25-to-1 in
the range from .5 v/cm to 20 v/cm.
HORIZONTAL-DEFLECTION SYSTEM
Sweep rates
Twenty-one calibrated sweep rates from 1
/Asec/cm to 5sec/cm. Accuracy typically with
in 1% of full scale; in all cases, within 3% of
full scale.
Magnifier
Expands sweep 2, 5, 10, or 20 times. Calibra
tion of magnified sweep rates accurate within
3% for sweep speeds which do not exceed
the maximum calibrated rate of 1 [xsec/cm.
Unblanking
DC coupled.
Triggering signal requirements
Internal— a signal producing 2 mm vertical de
flection on either the upper or lower
beam.
