Math channel (average function) in MATLAB

Hi, I was wondering if you could explain how exactly the built-in function "average" works, i.e. the window size, time length etc.. Also, is it possible to implement it in MATLAB? I've tried but it didn't seem to work. I'm using Picoscope 5444D. Here are some details about my Picoscope 6 settings an...

Make sure you apply the same downsampling method when setting up the data buffers for the collection.
Thank you.

Re: Picoscope 2405A Oversampling Feature

Oversampling was a method used in our older devices. Instead with newer devices you can use Downsampling in particular the downsampling type PS2000A_RATIO_MODE_AVERAGE Reduces every block of n values to a single value representing the average (arithmetic mean) of all the values. Equivalent to the '...

Picoscope 2405A Oversampling Feature

Hi,

I'm using the PicoScope 2000 Series (A API) in MATLAB and was wondering if it's possible to do the resolution enhancement by turning on the oversampling feature. I read the Programmer's Guide and it seems that this feature is disabled.

Thanks
