Applications

The Tektronix 1502B was designed for field cable testing, telephone line troubleshooting, and transmission-line fault localization. The TDR (Time-Domain Reflectometer) principle measures the time it takes for an electrical pulse to reflect from a cable fault, revealing the distance to breaks, shorts, or impedance discontinuities. The 1502B became the standard portable TDR tool in telecommunications, electrical installation, and cable maintenance — used by technicians, field service engineers, and telecommunications companies throughout the 1970s through 1990s and beyond. This instrument remains in use today by legacy system maintainers and equipment enthusiasts. The service manual is an essential reference for anyone maintaining, repairing, or restoring a 1502B to working condition.
