Product Overview

The Chroma 52400 series is a PXI based SMU (Source Measurement Unit) card designed for highly accurate source or load simulation with high precision voltage and current measurements.

The SMU combines a four-quadrant-source with high precision and high speed measurement. This unique capability makes a SMU the ideal instrument in many parametric test applications ranging from ICs, two-leaded components such as sensors, LEDs, Laser Diodes, Transistors, Solar cells, Batteries and many other electronics devices.

To meet various test requirements, the 52400 series has 16 control bandwidths allowing user selection of a stable operation, multi-ranges combined with 18 bit DAC/ADC provide the best programming and measurement resolution and accuracy available at a sampling rate of up to 100k s/S. Special programmable output resistance allows user to set as internal series resistance of a battery thus makes Chroma 52400 series SMU an ideal tool acting as a battery simulator.

The 52400 series has a built-in patented hardware sequence engine that uses deterministic timing to control each SMU. This sequencer comes with built-in 32k readings storage memory, it allows for cross module/card synchronization and latency free output control and measurement. This measurement is possible as no PC communication needed during test process.

All Chroma 52400 SMU series units are designed for four quadrant operation for use by applications that require voltage/ current source or load simulation. During a load operation, the module is limited by the PXI chassis’ standard of 20W heat dissipation per slot.
