1. Check External Z-Axis Operation
a. Connect the leveled sine-wave generator output via a
50-!! cable and a T-connector to the CH 1 OR X input con
nector. Then connect a 50-Q cable and a 50-!! termination
from the T-connector to the EXT Z AXIS INPUT connector
on the rear panel.
b. Set the generator to produce a 5-V, 50-kHz signal.
