Master Your 400G Design
The Keysight N4391B is the most compact OMA solution of its class and combines industry-leading noise performance with a proven architecture and Keysight’s well-known, reliable and flexible vector signal analysis (VSA) software.

Target Applications
To keep up with increased symbol rates of 112 GBaud, a test instrument is required that can handle the baud rate classes of transceivers for 600 Gb/s to 1.2 Tb/s and even beyond, from the first day in advanced research through the development phase. Not only symbol rates are challenging, but also modulation formats are getting more demanding due to the higher-order quadrature amplitude modulation which require a step forward in noise performance.

The N4391B, based on the latest industry leading UXR Oscilloscope series, is the best-suited optical modulation analyzer to support these application requirements.
