Type C cable power measurement

[Sachin_Kudari]

I am looking for a  test setup to measure power in a type C cable  using Labview.

I found one solution with Total phase which has Labview drivers, has anyone tried it for power measurement ?

Regards,

Sachin

Do you mean a USB type C cable? Also how about a link to the Total Phase thing you are referring to.

Thanks for the reply. Yes I meant USB Type C.

Find the link to the Total phase power meter API,

They have API for C,C#, Python, .Net .

That device looks quite minimalistic. But it depends on what you are trying to measure. If you just need basic analysis of USB power distribution it probably will work. But if you are designing a USB device and need to test and analyze its power consumption over many different types of operation I'm not sure you could do that with this.

I would probably go for a more classical approach in that case with voltage, current and power meters, electronic loads and what else.

Thank you for the reply. We have a developed product and we just want to measure the power through the USB cable.

Do you have any other solution on this, if it suits us we can try it.

No, I don't have a ready made solution, but if your company designed this product, your development department certainly should own the necessary measurement devices to test such things as they would seem utterly essential during the development process. And you should be able to talk to them and find out how they measured this.

So how comfortable are you with programming? 

Since they dont have an API for labview directly you might have to hack it to make it work, they do have .NET so in theory you could make it work. I have worked with the beaglebone and it is extremely hackabel so depending on how good you are at hacking you could make it work one way or another. 

You could try getting something like this: 

https://www.amazon.com/MakerHawk-Multimeter-Voltmeter-Capacity-Resistance/dp/B07DCSNHNB/ref=sr_1_9?k...

it's so inexpensive you might as well, then see if you can talk to it.  Trying to find a Labview API or library for one of these things may take a few days of searching and reading. 

I would say in many profession situations the people that designed this will have the equipment to test it, as mentioned by @rolfk. They will probably have a lab power supply or a custom made USB interface board that allows them to directly measure the current with a lab multimeter or DAQ.

Thank you for the reply,  I will try your one of the solution.
