Application Notes

 

Relative Intensity Noise (RIN) Measurement
Semiconductor laser Relative Intensity Noise (RIN) is an important parameter that can cause significant degradation to the performance of fibre optic communications links. It is important for both laser manufacturers and systems designers to understand how RIN is measured to ensure reliable, accurate and repeatable results.

Hardware Triggering of Coherent Solutions’ PXI Optical Modules

PXI’s integrated timing and hardware triggering capabilities offer a number of advantages over more
traditional software-initiated measurements. Learn how to make the best use of the hardware triggering capability present in Coherent Solutions’ PXIe photonics modules.

 Hardware Triggering Application Note


 

Transient Testing in PXI

Until recently, measurements of power versus time were only available using expensive oscilloscopes and optical-to-electrical converters. These solutions required complex synchronisation and suffered from poor power accuracy and dynamic range in addition to requiring extra equipment.

With the TRACE capability of the optical power meters from Coherent Solutions, you can now capture accurate time domain power meter readings over the entire range of the power meter (>70dB).
