DC−50 MHz current probe P6042 complete Compatible with 50 Ω scope inputs Produced from 1967 to (?) Manuals Tektronix P6042 Manual (PDF)

The Tektronix P6042 is a DC to 50 MHz current probe introduced in 1967. It was designed by Cal Hongel.

The sensor contains a current transformer for HF and a hall effect sensor for LF/DC components. The amplifier combines DC/LF and HF signals.

The AM503, introduced about a decade later, is a redesign of the P6042 with removable probes.
