The Tektronix A6303 aka P6303 is a DC – 15 MHz, 100 A current probe that combines an inductive pick-up with a hall element for DC response.
It was designed by Dale Dorando (see background story on the AM503 page).
The A6303XL is a version with extended cable length and lower bandwidth.
It requires an AM503/A/B, AM5030 or 11A16 amplifier for operation. The A6303XL can only be used with the AM503B and AM5030.
The Tektronix 067-0865-00 and 067-0240-00 are calibration fixtures for the P6303.
