Infinity sensor<>oscilloscope

Hi, As I continue to investigate the possibility of using your sensor, I have a question regarding the connection of your sensor to the measuring equipment.

Could you recommend or describe how you connect it to an oscilloscope. Do you use some kind of SMA-BNC or do it some other way.

I would like to get an accurate result excluding the influence of the measuring equipment.

I would also like to know what measuring equipment and with what characteristics you recommend to use. Best regards, Maksim Gudov

Infinity Sensor

May 10

Hi Max,

Use a a 50 Ohm SMA to BNC cable with the MH4 to SMA adapter that comes in the kit we send out. Any 500 MHz scope would be fine, it helps if you have a maths channel that can do integration and offset, or you'd have to post-process the data to get current.

Kind regards,

Infinity Sensor

thank you very much for the advice.

Could you also tell me if you know of any convenient solutions in case of measuring HS?

Best regards

If you use the infinity sensor for this, e.g. on the drain of the upper device where dV/dt is small, you'll need to take care of the clearance, creepage etc. Rogowski coils have dV/dt problems, but you could try that, or a shunt measured with a good optically isolated voltage probe (expensive!).

In our application, the voltage level of the dc bus will not be high. I'm more interested in an integrated solution based on a differential probe.

If you know these.

Best regards
