GENERAL PURPOSE ELECTRONIC TEST EQUIPMENT

Test equipment that has the capability, without modification, to generate, modify, or measure a range of electronic functions required to test several equipments or systems of basically different designs [14] [16].

GENERATOR

A machine that converts mechanical energy to electrical energy by applying the principle of magnetic induction. A machine that produces ac or dc voltage, depending on the original design [5].

GENERATOR END

See INPUT END [10].

GERMANIUM

GETTER

An alkali metal introduced into a vacuum tube during manufacture. It is fired after the tube has been evacuated to react chemically with (and eliminate) any remaining gases [6].

GIMBAL

GLOW DISCHARGE

Discharge of electricity through a gas in an electron tube [18].

GRAMME-RING ARMATURE

An inefficient type of armature winding in which many of the turns are
shielded from the field by its own iron ring [5].

GRAPH

A pictorial presentation of the relation between two or more variable quantities, such as between an applied voltage and the current it produces in a circuit [1].
