Micsig has Optic fiber AND HF current Probes?!
gby:
The current probes might be a re-brand of the new Pintech current probes. See https://www.pintech.com.cn/en/h-col-123.html
The Pintech PT-350 has the same funky 60 Ap-p rating, is 50 MHz, 5 mm max wire diameter, and looks visually similar. Not sure where the 100 MHz one comes from since I did not see a 100 MHz Pintech version.

It most probably, again, works with an optical modulator, Mach Zenhder, Kerr effect, Pockels, or similar. Someone must be making this for them. One problem is that for auto adjustment the input signal needs to be removed.

Why would you do that instead of just modulating the laser diode current?

The Tek IsoVu (and probably the Lecroy as well) have the laser on the scope-side, so they must have an EOM in the probe head. Of course, if you get rid of power-over-fiber anyway and have a reasonably large battery instead, you might as well go all the way and move the laser to the probe head as well. Maybe you can even use a COTS integrated transmitter (but linearity and drift might be a challenge). I would love to see a teardown.

Not enough other specs line up and the body/casing is completely different in the photos so probably not pintech sourced. Equally its not sharing specs or casing with any Hioki probes so this might be a new entrant to the market.

350Mhz?
