Plug the unit into a Tektronix convertible
Oscilloscope and turn the power on.
the instrument to reach operating temperature,
about 2 to 3 minutes and free-run the sweep
at 1 millisecond/cm, Turn the MODE switch
to A O N LY and the A-channel P O LA R IT Y and
AC-DC switches to NORMAL and DC respect-
ively. Position the trace to about +2 cm with
the A-channel VE R TIC AL POSITION control.
Turn the MODE switch to B ONLY and the
B-channel P O LA R IT Y
to NORMAL and DC respectively. Position the
trace to about -2 cm with the B-channel VER­
T IC A L POSITION control.
Now turn the MODE switch to CHOPPED.
Two traces w ill appear on the crt screen.
Notice that the A-channel VE R TIC AL POSITION
control moves the upper trace and the B-
channel V E R TIC AL POSITION control moves the
low er trace. Increase the sweep speed to 100
microsecond/cm and notice that each trace
is composed of many start-duration elements.
The two channels are being switched at approx-
