ADS131M04EVM: continous data record

user4963713

Part Number: ADS131M04EVM

Hi,

is it possible to record long set of raw data to PC with ADS131M04EVM with highest sampling rate ie. continous data and not save from captured data?

Hello user4963713,

You can change the samples drop down menu and capture the maximum number of samples selected in that drop down with the highest sample rate. Haven't seen any issues with that.

The GUI takes data in chunks based on the number of samples selected so there's no traditional continuous time view like there is on something like an oscilloscope. As you said, recording a long set of data might be a good workaround.

Best,

Thanks Cole,

one more question: what is maximum number of samples?

Hi user4963713,

I don't have the EVM in nearby so I can't answer that right now but some of the newer GUIs can do up to 2 million samples. This is on an older GUI architecture but something like 65k is a good bet. Let me know if that is sufficient and I can give you a proper answer next week.

Best,

Hello Macias,

65k samples would mean only 1 second data record with highest sample rate. This is too short period.

2M samples means 30seconds which would be ok.

Hi user4963713,

Looks like it can do the 2M samples. Using the "Other" option will allow you to type in a customer number but not allow you to exceed the last 2,097,152 option.

Best,
