Agilent Technologies Inc. has introduced a waveform analyzer for verifying and validating high-speed electrical communications systems and components.

With residual jitter of below 50 femtoseconds, channel bandwidths to 50 GHz and integrated clock recovery to 32 Gb/s, the Agilent plug-in module 86108B precision waveform analyzer assists engineers testing IEEE 802.3ba (40-Gb/100-Gb Ethernet), Optical Internetworking Forum CEI 3.0, INCITS T-11 32G Fibre Channel and high-speed proprietary systems. Agilent claims the 86108B’s integrated precision time base and clock recovery design, with typical residual jitter below 50 fs rms, minimizes potential problems.

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 PLL response for accurate and compliant device characterization.

An 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 to reduce setup complexity, maintain signal integrity and make 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.

Agilent offers the 86108B with bandwidth options of 35 GHz and 50 GHz and clock recovery data-rate options of 16 Gb/s and 32 Gb/s. Both bandwidth and clock recovery options are upgradeable.
The Agilent 86108B precision waveform analyzer is priced starting at $80,000.
