High Speed Testing of High Brightness LEDs

Use a SMU instrument's unique pulsing, voltage, or current capabilities to minimize self-heating on HBLEDs and reduce the negative impact on measurement accuracy, as well as to eliminate the worries about damaging the device under test.

• Minimum programmage voltage and current pulse: 150 µs
• Maximum pulse current 10 A
• Maximum pulse power 1000 W

Chacterizing and Validating Sensor Performance

SMU instruments are the most accurate, reliable, and convenient way to characterize and validate sensors and transducers that can generate and measure ultra-low and low voltage or current signal during sleep and active states of operation. SMUs offer the widest operating range, sensivity, speed and accuracy to minimize false readings and test with confidence.

• Voltage and current measure resolution at 10 nV and 10 fA
• Best voltage and current measure accuracy at 0.012% and 0.02%
• Maximum sample rate at 1 MSamples/s

Creating Battery Discharge Models and Simulating Batteries

A graphical SMU Instrument can discharge a battery and create a model of the battery for use with a battery simulator. The model consists of both open circuit voltage and internal resistance as a function of the battery's state of charge. The battery simulator will then emulate the battery using the created battery model and can be used under various testing conditions to see how the product performs when powered by a battery under various conditions of discharge.

• 0.012% basic measure accuracy with 6½-digit resolution
• Enhanced sensitivity with new 20mV and 10nA source/measure ranges
• Wide coverage up to 105 V, 7 A DC/7 A pulse, 100 W max.
