Agilent Technologies claims that it has introduced the industry’s first phase noise application software and options for the digital communications analyzer (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. Plus, a new 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 is a multirate wide loop bandwidth clock recovery module that allows precision waveform measurements with a variety of signals, including spread-spectrum clocked. It reveals root causes of jitter through frequency domain analysis -- an effective and easy method for detecting jitter sources. Also, this solution can perform the analysis on both clock and data signals, so the root causes of data jitter can be related to system clocks.

In addition, the DCA-J offers three new functionalities for optical applications:

• 40 Gbps compliance with Agilent 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. Carefully controlled frequency response allows operation as a reference receiver and provides consistent and accurate eye mask tests. It can be configured at standard or FEC rates for OC-768, STM-256 and related specifications.
• DCA-J option 300 provides the same industry-accepted analysis now translated into the amplitude domain. This enables capabilities such as relative intensity noise (RIN) measurement, a common specification for optical transmitters. Option 300 also allows separation of interference parameters to extremely low probabilities, providing an accurate measurement of Q-factor, commonly used to estimate bit error ratio.
• Agilent's new Rev 7.0 firmware for the 86100C DCA-J enhances the system through a novel approach to the measurement of optical modulation amplitude (OMA), a common specification for optical transmitters.
