Accelerate Precision Optoelectronics Test
Manufacturing test engineers are under pressure to ship optoelectronic devices—from LEDs and VCSEL arrays to optical transceiver components—at high volume while meeting tighter specs and cost targets. Powering next-generation displays, 3D sensing, and high-speed interconnects, these devices require parallel, deterministic testing with precise synchronization and aligned optical/electrical measurements—capabilities often limited by traditional discrete instruments.
Application Requirements
- Scalable architecture for high-density multichannel testing
- Fast, accurate electrical (IV) and optical-electrical (LIV) measurements
- Tightly synchronized operations and closed-loop interaction with external equipment such as optical coupling mechanisms
- High throughput with multisite parallelism and simple parallel test execution
- Manufacturing workflows needing software automation and data traceability for improved overall efficiency
NI PXI-Based High-Throughput Optoelectronics Test Solutions
- An NI PXI chassis and controller integrate computing, power, cooling, triggering, and instrumentation into a compact, synchronized, scalable system from benchtop to production.
- High-density NI PXI Source Measure Units (SMUs) give fast, accurate IV control and measurement capability to evaluate power consumption, linearity, and thermal stability.
- NI PXI timing and synchronization modules coordinate triggers and clocks across SMUs and digitizers for deterministic, low-jitter multichannel measurements.
- Driver and API support enables test development in NI LabVIEW, Python, or C# .NET, accelerating integration into existing manufacturing test frameworks.
- Trigger/timing I/O and programmable routing simplify synchronization with third-party optical instruments and enable tight control of optical coupling mechanisms.
