ABSTRACT:
A waveform generator is provided which is capable of generating simultaneously a plurality of electrical signals which have different waveforms. The waveform generator is completely battery operated and is particularly useful in testing multichannel devices where power is not available for standard waveform generators. A voltage regulation circuit is provided which provides a regulated voltage from a battery pack for use by the waveform generator. The forward voltage-current characteristics of the base emitter junction of a silicon transistor are used as the basis for the generation of a reference voltage for the voltage regulation circuit to thereby susbtantially minimize the battery drain caused by the use of a voltage regulation circuit.
