Agilent/Keysight N4917B

The Keysight N4917B Optical Receiver Stress Test Solution automates characterization and validation of high-speed optical receivers through standards-compliant stressed receiver sensitivity testing. It generates repeatable, compliant optical stressed eyes to evaluate receiver performance under stress conditions, reducing test setup time by over a factor of 10 compared to manual methods.

– Technical Specifications
