Jitter analysis

Agilent has introduced what it claims is industry-first phase noise application software and options for the digital communications analyser (DCA-J).

The software allows phase noise/spectral jitter analysis of clock and data signals over a wide dynamic range of 50 Mbps to 13.5 Gbps.

An optical/electrical module provides optical transmitter test and 40 Gbps optical compliance test; an advanced amplitude analysis option offers new methods for optical modulation amplitude and relative intensity noise.

The 83496B clock recovery module for phase noise/spectral jitter analysis module allows precision waveform measurements with a variety of signals, including spread spectrum clocked. It allows phase noise/spectral jitter analysis of clock and data signals ranging from 50 Mbps to 13.5 Gbps.

The device and phase noise application software reveal root causes of jitter through frequency domain analysis. Also it can perform the analysis on both clock and data signals, so the root causes of data jitter can be related to system clocks.

It also has three new functionalities for optical applications: 40 Gbps compliance with the 86116C optical/electrical module; the 86116C can be used as a 65 GHz oscilloscope channel or switched to a reference receiver for 40 Gbps optical transmitter eye-mask test; it enables capabilities such as relative intensity noise (RIN) measurement, a common specification for optical transmitters; easy OMA measurements for the 86100C DCA-I: the latest Rev 7.0 firmware for the 86100C DCA-J enhances the system through a novel approach to the measurement of optical modulation amplitude (OMA). The general OMA test requires special data patterns. The 86100 C provides the correct OMA result for these patterns and has the added flexibility to provide an accurate OMA result for virtually any data pattern.
