Product Overview

TEKTRONIX TCP312 PROBE

The Tektronix TCP312 Current Probe is a split-core probe that uses both transformer and Hall effect technology. When connected to Tektronix oscilloscopes with TEKPROBE Level II, TekConnect (w/ TCA-BNC), or TekVPI (w/ TPA-BNC) interfaces, the Tektronix TCP312 probe makes current measurements and calculations simple and easy.

Features and Specifications of the TCP312 Current Probe include:

• Features:
  • AC/DC measurement capabilities
  • Automatic Scaling and Units
    • Requires a TDS TEKPROBE oscilloscope or a TekConnect oscilliscope with TCA-BNC
