Keysight N9068C Phase Noise Measurement Application

Manufacturer: Keysight
Model Number: N9068C
The N9068C phase noise measurement application transforms Keysight's X-Series signal analyzers into intuitive phase noise testers with frequency and time domain analysis and multi-touch screen operation. View the phase noise from frequency offset 1 Hz. View the phase noise behavior of the signal under test across decades of offset frequencies with the log plot. Use AM rejection in the log plot so that you observe only the phase component. Characterize phase noise related behaviors from different angles for various applications with multiple markers with various marker functions. Signal Tracking provides a simultaneous view of phase noise and delta frequency in time domain. Working with X-Series signal analyzer and an external mixer, it enables phase noise measurements with the carrier frequency to millimeter-wave and beyond.
