VOLTS/CM -- Provides
calibrated
deflection factors from
.05 to 20 volts/cm when

Position.
DC-AC -- Determines
whether input to plug-
in is DC or AC coupled.
MODE--A five Position
switch to allow either
amplifier to be used
independently, to pro-
vide for switching the
two amplifiers at an
arbitrary rate, to syn-
chronize the Switching
