Waveform Analyzer Module from Agilent
Waveform analyzer module.
Santa Clara, CA — Agilent Technologies Inc. has introduced a precision waveform analyzer for engineers involved in design verification and validation of high-speed electrical communications systems and components. With reportedly industry-best residual jitter (below 50 femtoseconds), channel bandwidths to 50GHz and integrated clock recovery to 32Gb/s, the Agilent 86108B precision waveform analyzer gives engineers confidence they are seeing the true performance of their designs.

This new plug-in module is the latest addition to the company's 86100C/D DCA wide-bandwidth oscilloscope family. Engineers testing IEEE 802.3ba (40Gb/100Gb Ethernet), Optical Internetworking Forum CEI 3.0, INCITS T-11 32G Fibre Channel and high-speed proprietary systems will benefit from the instrument's measurement performance. As data rates increase to 28Gb/s and beyond, accurate component characterization becomes more difficult to measure.

Using cabling to connect instrumentation degrades signal integrity, and performance margins are consumed due to non-suitable measurement systems. The 86108B's integrated precision timebase and clock recovery design, with typical residual jitter below 50fs rms, enable it to minimize potential problems.

With this plug-in module, the company's wide-bandwidth oscilloscopes meet the requirements of advanced technologies better than any other oscilloscopes on the market today.

Continuous data-rate coverage from 50 Mb/s to 32 Gb/s, peaking control and adjustable loop bandwidths to 20 MHz also allow the clock recovery circuit to provide a golden PLL response for accurate and compliant device characterization.

In addition to the performance benefits, the integrated instrumentation-grade clock recovery circuit allows the module to trigger directly from single-ended or differential data signals. This eliminates the need for a separate trigger input. The module also integrates high-bandwidth pickoffs and phase-matched cables, which significantly reduce setup complexity, maintain signal integrity and make it easy for users to start making accurate measurements quickly.

An auxiliary clock-recovery input circuit allows engineers to analyze extremely low-level signals, or signals that have been closed due to severe inter-symbol interference, by triggering the 'scope using a separate synchronous data (or clock) signal connected to the 86108B's auxiliary CR input. The on-board phase detector enables a flexible and accurate technique to determine PLL bandwidth/peaking on devices with either clock or data inputs and outputs.
