This module consolidates the functionality of multiple power supplies and multimeters into a single, high-performance system, delivering superior performance at a fraction of the cost compared to traditional desktop setups. It also eliminates the hassle of cable clutter and current loops. With onboard filtering, the module effectively removes RF noise that typically couples with circuits and cables. The power supply is fully isolated, with a shared ground across all four channels, eliminating the mains noise commonly found in standard setups (as shown below). A unified interface allows for quick, simultaneous control of all supplies, enabling fast and efficient measurements across any configuration.

The hardware is highly adaptable, allowing reconfiguration with new processing algorithms. Its interconnected design supports a wide range of intelligent operations. It can function as a basic power supply, current sensing, and I/O card, or be reconfigured for advanced tasks such as amplifier bias control, transistor IV curve measurement, leakage current testing, and detecting potential static damage in devices. Pulse measurements, for high-power devices, can be conducted with pulse durations from 1 µS and longer.

The system is capable of collecting data from various sources, with an interface protocol that ensures simultaneous data transfer. It also includes a configurable audible alarm for alerts related to overcurrent, specific input voltages, or digital events. LED indicators provide clear visibility of all external connections, making it easy to monitor the module’s status at a glance.

Constant Voltage, Current and Power Mode

The module can control the output to be either constant voltage or constant current. When switching between these modes the device limits overshoot and protects the DUT. Custom software modules can be added to provide any simulation of power interface that may be required.

Pulse Measurement Capability

The power line outputs can be pulsed to measure high power devices. Pulse lengths upwards of 1us can be made. Maximum voltage rise/fall time is 10V in 100nS. 1MSPS of voltage and current are made during the pulses.

Controllable Start / Stop Rate (soft start)

The module can be configured for immediate or slow ramping to achieve the target output voltage. This is especially useful to minimise overshoot when high inductance lines are present.

Sequence Programming using Trigger In / Out

The module can be pre-programmed with a sequence of measurements, events and sweeps. The unit can be triggered enabling fast and aligned sequencing through large numbers of tests. Onboard memory is available for collection of large amounts of sample data.

Fast Sequence Sweeping

Voltage / Current for quick device characterisation. IV curves can be taken for transistors, diodes and any semiconductor devices enabling leakage, ESD damage or verification of bond wire attachment. Multiple pins can be sweeps concurrently enabling ultra-fast die measurement. Analog Input can be used within the sequencing – for example diode measurement.

Programable Measurement Settle Time

The dwell time for a current or voltage sweep can be programmed to ensure the DUT is fully settled. This control can also be automated to ensure all data points are steady state measurements. This process ensures the most rapid of sweeps.

Accumulated Charge Measurements

for IOT and Accurate Battery Simulation. The unit can simulate accurate batteries for IOT measurements and assessment of battery performance under various conditions. The unit can detect Pico amp current draw with averaging and hundreds of samples / second allowing even the fastest of current blip to be measured.

Software Applications

is available for basic control and quick start of the unit. The unit can also be easily communicated with options using GPIB, RS232, USB, Ethernet via all programming environments (C / Matlab / Labview etc).
