The SpikeSafe Source Measure Unit is a precision pulsed source measure unit that precisely sources pulsed current and simultaneously digitizes voltage. Optimized for precise and repeatable high-power LED and laser testing, SpikeSafe™ SMU (Source Measure Unit) current sources deliver precise pulsing with low microsecond rise times, low-jitter triggering and integrated digitizer for more accurate and repeatable high-power LED and laser testing. Combined with Vektrex easy-to-use Control Panel software application, use the fast pulse Source Measure Unit to quickly and easily sweep and generate IV curves.
SpikeSafe SMU supports applications with currents to 10A and as low as 50mA.
See High Current SMU for applications requiring currents to 60A.
Device junction heating distorts measurements, causing L-I curves to droop and shifting I-V curves. With Vektrex’s fast pulsing SMUs you can make your measurements before heat builds up, revealing true device characteristics.
The SpikeSafe SMUs feature general operational modes including DC, Continuous Pulse, Single Pulse. Specialized operational modes including Sweep, Burst, Repetitive Burst and others are hardware integrated for ease of use. Minimum pulse widths as low as 1us reduce junction temperatures for VCSEL, laser diode and other semiconductor devices. SpikeSafe SMUs can power a broad range of applications with sustained output power and no duty cycle limitations.
Test What You Couldn’t See
With more and more high-power density LED and laser devices coming to market, there’s a gap between what can tested with traditional source measure units and present engineering and production testing needs.
