Description
Tektronix TCP2020 – 20A 50 MHz BNC AC/DC Current Probe
The Tektronix TCP2020 is a premier universal AC/DC current probe engineered to deliver elite operational performance for characterizing electrical stimulus up to 20 A RMS across a wide range of measurement platforms. By addressing the requirement for versatile current oversight in general-purpose laboratory settings, this instrument utilizes a BNC interface and a separate AC power adapter to effectively minimize measurement uncertainty on any instrument with >100 kΩ termination. The metrological architecture of the TCP2020 ensures absolute traceability, featuring a 50 MHz bandwidth and a 10 mA/mV sensitivity for surgical acquisition of high-speed switching signals.
Built for industrial longevity, the TCP2020 is a high-trust solution for managing stimulus in power supply design and electronic maintenance, featuring a split-core jaw for tool-less circuit integration. Its technical sophistication is centered on its 1% DC gain error accuracy and manual offset adjustment thumbwheel, establishing it as a professional-grade metrology asset for technicians requiring a mobile current standard. Providing the repeatable results and rigorous verification necessary for maintaining system safety, this probe serves as the definitive tool for engineers requiring high-resolution current indication combined with broad oscilloscope compatibility.
