Coherent Transmission Test Instruments

For coherent transmission test Keysight offers instruments for the generation and analysis of complex modulated optical signals. Multichannel arbitrary waveform generators are typically used to synthesize complex modulated signals.
Optical modulation analyzers provide detailed insights into the complex modulated optical signals at the physical layer to determine signal quality or evaluate components that are designed for IQ modulation and demodulation.
Keysight offers the widest range of optical modulation analysis and synthesis instruments for testing up to 1 Tb/s – for your current and future needs.
