The Ametek/Elgar PIP9012A-1T-311 is a digital/analog programmable plug-in oscillator engineered for seamless integration into Elgar SL, SX, and DMAC II series AC power sources. This extended-range variant delivers precise waveform generation and signal conditioning via front-panel keyboard control and GPIB (IEEE 488-1978) command architecture. The unit combines manual and remote programmability to support custom test scenarios within integrated measurement systems.
