The Tektronix CT1 Current Probes are designed for permanent or semi-permanent in-circuit installation.The CT1 probe consists of a current transformer and an interconnecting cable.

The current transformers have a small hole through which a current carrying conductor is passed during circuit assembly. The P6041 Probe Cable provides the connection between the CT1 and CT2 Current Transformers and a BNC oscilloscope input.

A 50 Ohm termination is required to terminate the cable when connected to a high impedance (1 MOhm) oscilloscope input. One probe cable can be used to monitor several current transformers that have been wired into a circuit 
The CT-1/ CT-2 Current Probes are pictured here with the P6041 BNC Probe Cable.
