More Information
ModelTCP305A

The Tektronix TCP305A Current Probe uses split-core transformer and Hall effect technologies for accurate AC/DC measurements up to 50 A. It supports TekProbe, TekConnect (with TCA-BNC), and TekVPI (with TPA-BNC) interfaces, offering automatic scaling, reduced noise, and on-screen oscilloscope readouts.

Ideal for precision power analysis in semiconductors, telecom, power inverters, and mobile communication applications. Delivers high accuracy (±1% typical), low insertion impedance (0.035 Ω at 1 MHz), and handles peak pulse currents of 50 A.

Testwall can supply the used Tektronix TCP305A, fully tested. With expert support and global delivery, Testwall ensures high-performance instrumentation with unmatched reliability and service quality. Please contact us directly if you need calibration or repair of the Tektronix TCP305A.
