Old Tektronix A6302 current probe with new TCPA300 amplifier
« on: October 09, 2019, 12:07:39 pm »
Hello,
someone know if it is possible to use the older A6302 (or A6303) current probe on the recent TCPA300 amplifier ? In other words, if I change the connector of the A6302 could I connect it to the TCPA300 ?

Here is the picture of the TCPA300 male connector, anyone know the connector brand ?


Thanks

It is kinda-sorta possible, but requires some kind of adapter that's more than 1:1 pins, especially Hall supply used to be +-3V in the old ones and is +-5V in TCPA300. Additionally, in TCPA300 there is no input for HALL_OFFSET signal as apparently this is done in the probe (new probes).

Also, PROBE_ID resistances are different in the new probes and while I got some measurements from new probes to replicate, when used on A6032 the scale factors don't match what's on the TCPA3000 display (A/V), so custom probe scaling in the scope is needed for every TCPA300 range.

TL;DR Possible, not easy, not super practical.
