Tektronix 80E04 Sampling Module

The Tektronix 80E04 is a high‑performance electrical sampling module designed for high‑speed serial data and TDR (Time Domain Reflectometry) measurements, compatible with Tektronix sampling oscilloscopes. It features dual TDR channels, independent probe power switches, 50Ω input impedance, and a maximum input voltage of ±3V, supporting precise high‑frequency signal integrity analysis. This module enables accurate testing of high‑speed digital interfaces, transmission line impedance, signal reflection, and high‑speed serial communication circuits. Used unit in excellent working condition, fully tested and calib
