Nice frequency response on the website - but one moment, I´m just reading "simulated" below the graph. Do you have a measurement?

I do not know if advertisements of this kind are okay but if they are, can you please specify a price range?

Can you share some details of the probe construction? What material do you use for magnetic shielding? Do you use mu-metall or metglas?

Where are you from? It´s absolutely not creating confidence if a website has no impressum with a real-world-address.

Hi Phil,

On your questions.

Yes few sine wave measurements have been done to probe the bandwidth and it looks close to what simulation shows.
Frequency measurement can be found on the site of the original design https://github.com/westonb/rogowski-relief/blob/master/doc/images/hf_bode.PNG
More precise measurements will follow.

I am not sure if advertisements of this kind is okay too.

RP8025 is using aluminum extruded enclosure.

A probe (together with the USB power cable and the adjustment screw driver) costs 105Euro (shipment not included in this price)

The mechanics Rogowski coil and product assembly is done in Bulgaria
The PCB and electronic components assembly is ordered from China.

You are right our address added on the web site.

Thank you,
Dimitar
