Agilent precision waveform analyser

A precision waveform analyser is a plug-in module and the latest addition to the 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 measurement performance.

The integrated precision timebase and clock recovery design has a typical residual jitter below 50 fs RMS.

Continuous data-rate coverage from 50 Mbps to 32 Gbps, 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 characterisation.

The integrated instrumentation-grade clock recovery circuit allows the module to trigger directly from single-ended or differential data signals and the module also integrates high-bandwidth pickoffs and phase-matched cables.

An auxiliary clock-recovery input circuit allows engineers to analyse extremely low-level signals, or signals that have been closed due to severe intersymbol interference, by triggering the scope using a separate synchronous data (or clock) signal connected to the device’s auxiliary CR input.

The 86108B has bandwidth options of 35 and 50 GHz and clock recovery data rate options of 16 Gbps and 32 Gbps.

Features include intrinsic jitter (<50 fs RMS typical); clock-recovery range (50 Mbps to 32 Gbps); high-bandwidth receivers (35 and 50 GHz options); integrated triggering architecture, allowing simple connection schemes, analysis of low-amplitude signals and the elimination of the clock-data delay; an internal phase detector that enables accurate measurements of PLL bandwidth, jitter transfer and jitter/phase noise spectrum.
