a. Test setup is shown in Fig. 6-19.
b. Connect a short jumper lead between R144 and the
— 100 V supply, as shown in Fig. 6-20.
d. Conned a I-kHz square-wave signal from the square-
wave generator through a 50-ohm termination, a 50-ohm
cablo, a UHF T connector, and a 47-pF Input Time-constant
Normalizer to tho HORIZONTAL -f INPUT connector, in
the order given.
c. Connect a 10X probe from the VERTICAL + INPUT
connector to pin 8 of V I60, as shown in Fig. 6-20.
