Product Information

The AXS844x Source and Measurement Unit family is designed for high throughput semiconductor testing. It is perfect for the very fast and precise measurement of e. g. LEDs, MOSFETs and diodes.

The linear output stage with a very short rise time allows current pulses up to 100A. Three voltage ranges (100V, 200V, 400V) and ten current ranges (from 20μA to 100A) allow accurate programming of the output.

With two integrated measurement units for voltage (VMU) and current (CMU) all high current tests of power semiconductors can be done.

The AXS844x devices are able to generate current- or voltage pulses with automated measurement after a programmed delay. A versatile trigger engine with different trigger in- and outputs allows synchronization with additional equipment.
