20A Sources and Source/Measure Units from Vektrex are versatile instruments that provide accurate pulsed current and DC constant current.
Pulse precision, lack of duty cycle limitations, and simplified output wiring make these ideal foundation instruments for reliability test systems, automated component test systems, interactive optoelectronics R&D benches, or in-house calibration stations for LED, Laser Diode, VCSEL and other semiconductor devices.
These cost effective tools supporting semiconductor component test are available in single or multichannel modules and at other power levels.
20A SpikeSafe Source Measure Unit and Specifications
The 20A SpikeSafe Source Measure Unit (SMU) is an award-winning High Current SMU; a member of the SpikeSafe Source Measure Unit Family. Like other Vektrex SMUs output pulses have nanosecond rise and fall times – key to precise and repeatable LED, LIDAR, and VCSEL photometric and electrical measurements. This pulsed high current SMU supplies precision DC, continuous pulse, and single pulse current with excellent pulse fidelity

Video: Use a Source Measure Unit for “Crazy Stable” Measurements
Vektrex claims the SpikeSafe Source Measure Unit produces “crazy stable” measurements. In this video, we compare the voltage measurements of the Vektrex SpikeSafe SMU’s internal digitizer with those of the Keithley DMM7510 on the same load – paying close attention to the stability of the entire Vf pulse capture from each unit.
