Arbitrary Generator to Control Power Supplies

01 October 2010 - The company Maren Ewert - introduced with the arbitrary generator AWG S1 an inexpensive, external control unit, which in a simple way can control power supplies via its analog interface.

Arbitrary waveform generators provide higher flexibility than function generators (only applicable for standard curves such as sine, square, triangle and saw tooth) due to the ability to save and give out any (arbitrary) and curve trajectories.

One of the special characteristics of the AWG S1 is the simple handling and the broad range of functions. Even complex curve traces are created in with minutes as a CSV file and transferred via USB interface to the internal microSD-card. Afterwards the arbitrary generator can be used without computer assistance.

The AWG S1 has two analog outputs, which cover a voltage range of 0 to 10 V. This way both, the voltage waveform as well as the current output of the power supply can be controlled at the same time. If only voltage or current needs to be controlled, the AWG S1 can control two power supplies in parallel.

Up to 500 different curves can be stored on the changeable microSD card, each with up to 5,000 data points. The time interval between individual data points may lie in the range of 1ms to 119h, so that wave forms are possible over very long periods of time.
