Micsig has Optic fiber AND HF current Probes?!

According to their previous pricing policy in overseas markets, the new 50A probe should not be so expensive, my guess would be 1500$, tops.

Well, let´s see when the probes will appearing on the batronix website..

Today I received via email a nice PDF flyer direct from Micsig for the CP500/1000 series current probes, suggesting they are finally bringing these to the US market. No US pricing info, and they direct you to "please contact your local distributor to get the special offer for NEW Micsig High Frequency AC/DC current probe!" Sadly they don't list who their US distributors are but I presume that will be forthcoming.

I'm thrilled they're releasing these as the available choices for high bandwidth clamp current probes has always been very limited. Of course, so is the total market for them.

I'm not too happy with their minimum measurable current, though. The 6A version lists 20mA as the bottom end. It's not unusual at all to want to view current behavior below double digit milliamps.

I don't think the market is that small. They're very useful for a lot of power electronics work. It's just that the market had been dominated by (from highest to lowest performance) Tektronix, Hioki and LEM and their various rebrands (Lecroy, Keysight) so far, and people have been forced to pay their prices. If this is an original design, and not another probe made by Hioki, then I'm curious about the performance.

No, indeed, since you can fly to the moon and beyond on 20 mA these days. This suggests that the gain of the Hall-effect sensor is lower than Tek and Hioki: less sophisticated sensor or attachment to the ferrite core. You can increase the sensitivity by wrapping multiple turns of the wire around the probe, but that increases insertion impedance.

I can sell the 50MHz CP502B version for under US$500
