Description
Overview
The Vektrex PSMU-PRF-4-10us is a 4A SpikeSafe source measure unit designed to accelerate test system performance with precision and accuracy. It delivers fast pulses with nanosecond rise times that keep junction temperatures low during LED, VCSEL, and laser diode testing. The integrated low-noise digitizer with 400V high-range capability provides accurate voltage measurements synchronized with fast pulse delivery.
Key Features
- 4A output current with nanosecond rise and fall times (200ns–3µs)
- Integrated low-noise digitizer with 400V measurement range
- Multiple operational modes: DC, continuous pulse, single pulse, sweep, burst, and repetitive burst
- Smart measurements: full waveform capture with heating curve or precise single-point measurements
- Integrated BIAS source with JEDEC ETM support for junction temperature measurements
- SpikeSafe load protection with continuous monitoring and automatic shutdown on anomaly
- 500W total output power
Applications
- LED photometric and electrical characterization
- VCSEL testing and evaluation
- Laser diode testing
- Junction temperature measurement
- High-speed pulse and transient analysis
