The Elgar 9012 Plug-In Programmable Oscillator is well suited for applications such as pass/fail incoming inspection testing. It has a 12-pad keyboard for local control. It offers 2 methods of creating zero crossing voltage drop-outs for power line problem testing. Zero, peak or random commands give users control of the point on the sine wave for the voltage and/or frequency change to occur. The 9012's unique programmable frequency range achieves a maximum resolution of 0.01 Hz from 45 to 99.9 Hz, 0.1 Hz from 45 to 999 Hz, and 1.0 Hz from 45 to 5000 Hz, with accuracy of 0.001% of programmed value. Output voltages of 0-135 VAC or 0-270 VAC can be remotely selected. Programming from zero volts to full scale takes less than 1millisecond to within ±1% of full scale, and 50 milliseconds to within ±02% of fuII scale. Programming from 5% or greater of full scale to full scale takes less than 1 millisecond to within ±0.2% of full scale.
