  • Trigger in- and outputs
The potential-free multi-channel SMUs of the AXS family can output regulated DC voltages or voltage pulses in the range from -50 to +400 V. The signal curve is very linear and is characterized by very short rise and fall times. The extremely fast regulation prevents the output signal from overshooting, which enormously shortens test times.

Functions such as the start of a pulse can be activated by hardware triggers and thus guarantee very short response times.

With the integrated switching matrix, the individual functional units (generator, VMU and CMU) can be flexibly connected to the test items. This means that basically three different devices are available for each channel. Complex test scenarios can thus be implemented with just one device. A wide range of switching options are available to the user via additional I/Os for controlling external relays.
