The SpikeSafe SMU

SpikeSafe SMU 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 microsecond rise times, low-jitter triggering and integrated digitizer for more accurate and repeatable high-power LED and laser testing.  Pair SpikeSafe Source Measure Unit with Vektrex developed Control Panel software application to quickly and easily sweep and generate IV curves.

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. Inadequate power, pulsing and measurement capabilities limit previous generation source measure units.

SpikeSafe® SMU precision pulsed source measure units close that gap by providing accurate pulsing from hundreds of seconds down to 1us with sustained output power. SpikeSafe SMU brings together the speed and power needed for LED and laser testing with integrated high-speed digitizing measurement. Now you can accurately test what you previously couldn’t test, and see what you didn’t have the power to see – with remarkable repeatability.

Introducing “crazy stable” measurements

SpikeSafe SMUs provide the power needed for more accurate, efficient and repeatable measurements.

The SpikeSafe SMU features submicrosecond to low microsecond rise/fall times, programmable load tuning and on-the-fly pulse width correction. Together these mean the device under test experiences less heating and more uniform heating. The result is unmatched measurement stability – measurements described by one beta site evaluator as “crazy stable”.

One and done measurements. No averaging required.

Precision timing with a low-noise integrated digitizer eliminates the need to average multiple measurements.

With measurement stability, multiple measurements and averaging is not required speeding test. With measurement stability, false positives and false negatives are eliminated, improving yield and reducing the cost of test.

SpikeSafe SMUs provide the power needed for more accurate, efficient and repeatable measurements. Available in full and half-rack sizes, SpikeSafe Source Measure Unit’s flexibility powers DC, continuous pulse and single pulse current modes for the devices of today and tomorrow. 

Precision timing with a low-noise integrated digitizer eliminates the need to average multiple measurements. SpikeSafe SMUs provide the power needed for more accurate, efficient and repeatable measurements.

SpikeSafe SMUs supply precise static and dynamic current output modes including DC and continuous or single pulse modes. Minimum pulse widths as low as 1us reduce junction temperatures for VCSEL, laser diode, and other semiconductor devices. With sustained output power and no duty cycle limitations, SpikeSafe SMUs power a broad range of applications.

Easy-to-Use Control Panel Software Application

Vektrex’s easy-to-use Control Panel Software Application provides turn-key control of the SpikeSafe current sources and optional high-speed sampling voltmeters and spectrometers. This software pairing provides familiar LED and laser/diode source/measure capabilities including sweeps and IV curve generation. With the added benefit of high speed sampling, pulse visualization, and light measurement.
