Tektronix 80E04 TDR Sampling Module

Overview

The Tektronix 80E04 is a dual-channel Time Domain Reflectometry (TDR) sampling module designed for precise characterization of high-speed interconnects and transmission lines. With 20 GHz bandwidth and 23 ps incident rise time, it enables accurate impedance profiling, crosstalk analysis, and S-parameter measurements on complex PCB layouts and backplane structures.

Key Features

• Dual-channel design with independent step generation for true differential measurements
• 20 GHz sampling bandwidth with 23 ps incident and 15 ps reflected rise time
• Independent incident and receiver deskew for fixture and probe de-embedding
• Selectable step polarity for differential or common-mode TDR testing
• Optional 2-meter remote sampler extender for improved signal fidelity
• Precision microwave connectors supporting standard probe types

Applications

• Transmission line quality and impedance profile characterization
• Differential and single-ended TDR measurements on coupled transmission lines
• Crosstalk analysis on multi-conductor interconnects
• S-parameter and impedance measurements with Tektronix IConnect software
• Impedance compliance testing for high-speed serial data standards
