I ordered one too ... AC bandwidth is anyway much better than an usual clampmeter ~400Hz - 1KHz It should be easy to test what is limiting the bandwidth by replacing the hall outputs with the signal generator ... But the quality of the core is very important so I don't think the circuit is the limiting factor . |

I was also going to order one; that's how I found this thread but I'm kind of reluctant since I was going to use it for taking screenshots of current plots directly from my scope. Since I want the waveforms to be as accurate/nice as possible this is just not going to cut it unfortunately. Maybe I would be better off with plotting software than this. See here: https://youtu.be/uZTicR_eC9A?t=521 I'm not sure if the triangular waveform would actually look like a triangle if frequency was lower.. If signal is okay for say a frequency of 10k that's fine enough for me at least. Perhaps someone who has this probe could post some screenshots in different frequency ranges. |
| CDaniel:
This is usefull only when you can't interrupt the circuit , otherwise a proper shunt will give you all the bandwidth ... As I see it , it is suitable for field measurements with a portable oscilloscope , not in the lab . |

Which Opamps are used within the clamp? |
