Can the Picoscope SW apply several math operation in the trace? For example can you plot

integral(Channel A * Channel B)*5

## Math functions

### Re: Math functions

Yes it can.

If you don't already have a scope and software I would suggest downloading a copy and running it in demo mode to see what can be done. There is a video covering Maths Channels here

### Re: Math functions

I would like to do the following math function:

(chA - DCAverage(chA))^2

I would then like to do a waveform average of the result.

Can Picoscope 6 software do this?

(chA - DCAverage(chA))^2

I would then like to do a waveform average of the result.

Can Picoscope 6 software do this?

### Re: Math functions

You may find that the following Maths equation will work
integral(A) will perform the DC average for the current waveform

average(function) will perform the average of multiple buffers

Code: Select all

`average((A-integral(A))^2)`

average(function) will perform the average of multiple buffers

### Re: Math functions

this seems to work. I can't easily get the result to display properly. Since I'm a newbie with this software, I don't know how to scale the y-axis for a view containing the result. Are there keyboard shortcuts?

### Re: Math functions

No shortcuts, the scales get defined when you create the maths channel. To change them you would need to go back in and manually edit the ranges to get a sensible display.

Any maths channels that have components which are influenced by the time axis, integral in this case, can have these issues, particularly if you change the timebase.

We do have a feature request in to normalize the maths channels on the display, but not sure when this will be implemented.
