Features & Benefits
The MPIV – Modular Pulsed IV is used for High Power current & voltage characterization of semiconductor devices. It is also well suited for applications requiring precise high current and voltage pulses. The Drain Pulse Module (DPM) uses an external high-current supply while the Gate Pulse Module (GPM) has an internal high-precision voltage supply. Additionally, the MPIV can be synchronized with an external or internal trigger.
The DPM is the core of the system. Its internal microcontroller uses precision Pulse Width Modulation (PWM) modules with complementary outputs and programmable dead-time in order to generate and synchronize the pulses for both drain and gate bias. The pulse width is adjustable from 200ns to 2ms; pulse repetition rate from 500Hz to 1MHz, with a maximum duty cycle of 50%. Two internal N-channel MOSFETs within the drain module support voltages up to 200V and currents up to 17A. Both the pulse and
quiescent bias voltages are delivered via external DC power supplies thereby making the Modular Pulsed IV a customizable solution.

Setup
Specifications
Setup
The GPM operates as a slave module controlled by the DPM. Internal precision Digital Analog Converters (DAC) are used to adjust the gate voltage in the range of ±10V, with a 5mV resolution. The output buffer amplifier delivers up to 100mA.
Voltage and current measurements are performed using a high speed 4-channel digital oscilloscope. Voltages are sampled directly on the gate and drain bias-tee sense terminals; the drain current is measured using a high-speed high sensitivity current probe.
