Hello,
Firstly, I'm sorry for my bad English, I'm French...
My question : I have measured an instantaneous and RMS current with my Pico product. So I have now two curves.
I just want to know if it's possible to calculate the RMS current from the instantaneous current without need to do an other measure. I was searching for a function in the "Maths Channels" but I didn't find.
That's the function I want to calculate.
Is it possible ? If yes, can you help me please ?
Best regards,
François

Re: RMS current function
You can see an example in the attachment.
I'm searching to write in "Maths Channel" a function which is able to calculate the red curve from the blue curve...
Thanks

Re: RMS current function
Can you save your waveform as a csv file and post it here then we can take a look to see if it is possible to create the maths channel.

Re: RMS current function
You can see in the attachment the csv file and the original file...
If you need to have others measurements, I can do it without problem.
Thank you

Re: RMS current function
I haven't been able to create an equation to do this.
Has anybody else had a go ?

Re: RMS current function
Hi,
We have found a component which is able to do the conversion from the instantaneous current to the RMS current, this is the reference : AD536A.
If you need to see technical informations, you can go here :
http://pdf1.alldatasheet.fr/datasheetp ... D536A.html
My question : is it possible to integrate the component or at least its function to the Picoscope ?
Thanks,
François

Re: RMS current function
It is unlikely that we would be able to integrate the component into Picoscopes. You could contact support@picotech.com for a definitve answer as to whether the functionality could be added.
