The Tektronix CT-1 (015-0040-00) Current Transformer is part of the P6040 current probe system. It has a #6-32 threaded stud on the end opposite the output SMA connector to allow it to be mounted wherever it is needed. Several CT-1s may be mounted in one assembly under test and monitored, in turn, by a single P6040.

It was designed by Murlan Kaufman.
