The VX-Instruments VX-AXS8444 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 or diodes. The linear output stage with a very short rise time allows current pulses up to 100 A. Three voltage ranges (100 V, 200 V, 400 V) and ten current ranges (20 μA … 100 A) allow accurate programming of the ouput. With two integrated measurement units for voltage measurement (VMU) and current measurement (CMU), all high current tests of power semiconductors can be done. The VX-AXS8444 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 synchronisation with additional equipment. Due to the modular concept of this unit, it is easily possible to customize the power stage and output specification. The hardware architecture of the AXS8444 family supports output currents up to 100 A and output voltages up to 400 V. The maximum static output power is limited to 800 W and the maximum pulse output power can be up to 10 kW. A mixture of output channels with different specifications is possible.
