In addition to the performance benefits offered by the Agilent 86108B, 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.
Characterizing Closed Eyes and Phase-Locked Loop Designs
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.
Economical and Upgradeable
The integration of several instrumentation blocks in the 86108B provides significant cost advantages in addition to the highest measurement accuracy. The cost of the system (an 86100D mainframe plus the 86108B module) is far below any comparable real-time or equivalent-time oscilloscope solution. Additionally, 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, so users can enhance their instruments as their designs warrant.
Benefits of the Agilent 86108B precision waveform analyzer include:
• Lowest intrinsic jitter (< 50 fs rms typical), which provides the most accurate measurement waveforms.
• Widest continuous clock-recovery range (50 Mb/s to 32 Gb/s), allowing for easy measurement setup and compliant device characterization.
• High-bandwidth receivers (35-GHz and 50-GHz options), providing a faithful and accurate representation of the incoming signal.
• Integrated triggering architecture, allowing simple connection schemes, analysis of low-amplitude signals and the elimination of the clock-data delay that can corrupt jitter measurements.
• An internal phase detector that enables accurate measurements of PLL bandwidth, jitter transfer and jitter/phase noise spectrum.
