W9068A Phase Noise Measurement Application for CXA

The W9068A is discontinued after June 1, 2019. The replacement model is the N9068EM0D X-Series Measurement Application with KeysightCare.

Signal analysis

• One-button measurements for analyzing phase noise in frequency domain (log plot) and time domain (spot frequency)
• Compatible with phase noise measurement personality in Keysight ESA spectrum analyzers
• Runs inside CXA signal analyzer

Measurements

• Log plot: Phase noise view in frequency domain including DANL floor and integrated noise measurements along with spurious table
• Spot frequency: Phase noise view in time domain including carrier frequency drift measurement
• Monitor spectrum: Easy-to-use simple spectrum view for a quick check of your signal
• IQ waveform: Easy-to-use simple time domain view

Performance (hardware dependent)

• Phase noise density accuracy: up to ±0.91 dB
• Offset frequency accuracy: Offset < 1 MHz, negligible error
• Base instrument phase noise (typical with center frequency = 1 GHz) -110 dBc/Hz

Other features

• License key upgradable
• Fixed and transportable license available
• SCPI remote user interface

The W9068A phase noise measurement application for the CXA is one in a common library of more than 25 measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements and software. Transforming the CXA signal analyzer into a phase noise tester with convenient one-button operation, automating the measurement procedure.

Phase noise measurements

• 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
