c. Check— Overshoot or ringing maximum 0.8 mm (0.4
minor graticule division) on a 4 cm signal. See Fig. 5-7.
16. Check 50 Me Response:
a. Requirement— Sufficient control of amplitude of a 50
MHz signal should be available to the test oscilloscope
vertical am plifier input, for High Frequency Sync checks, etc.
b. Set the Type 191 Frequency Range selector to 42-100,
the Frequency dial to 50, and the output amplitude controls
for a 4 Volt output.
c. Properly terminate the Type 191 and apply its output
to the 067-0521-00 EXT INPUT.
d. Change the TEST FUNCTION switch to HIGH LOAD
and turn the VARIABLE control fully clockwise.
e. Check— The signal amplitude should be 2.5 cm or more.
See Fig. 5-8.

f. Turn the VARIABLE control fully counterclockwise.

17. Check G A IN SET:
a. Requirement— Input signal division ra tio .o f 250:1, accu­
racy 1%.
b. Turn off the test oscilloscope and remove the 067-0521-
00
.
c. Change the TEST FUNCTION switch to G A IN SET and
connect pin 10 of the interconnecting plug to chassis ground
with a short jumper. See Fig. 5-10.
