These are crazy expensive for what they are — even second hand and out of calibration.
As far as I can guess the CT-6 current probe is just a moulded miniature toroid with 10 turns of thin wire attached to an SMA terminated 50R coax.
Does anybody have an insight what ferrite material is used in these?
I am thinking a Coilcraft or Mini-ciruits impedance matching transformer or a core from an ethernet pulse transformer. Two inches of 32 gauge magnet wire. SMA pig tail. A drop of epoxy.
Would this work?
