ADS124S08EVM: EVM Software, Data analysis tool

Part Number: ADS124S08EVM
Other Parts Discussed in Thread: ADS124S08

Hello

I have some questions for ADS124S08 EVM software.

1.
In the software, "Data Analysis Tool" is the tool to collect the data.

But I feel this tool can only get one channel data. Is it correct?

I want collect 3 different channels by changing internal MUX. How can I do it?
Is it possible by using script?

2.
Could you tell me the maximum number of points for "collect  Data" (below)?

Regards,
Oba

    Hi Oba,

    You are correct in that the Data Analysis only collects data for the current mux configuration.  You cannot layer several different measurements together.  You would need to capture data from one mux channel, then store the information to a file, change the mux settings, capture data, and store the data to a file, etc..

    You could setup the mux changes and data capture in a script, but there is no provision for writing the data to a file once captured.  So essentially this would still be a manual operation within the script.  You might find the information useful in the Appendix B.1 of the user's guide:

    https://www.ti.com/lit/ug/sbau260/sbau260.pdf

    As far as the maximum number of samples that can be collected at one time the number is 1048576 (or 2^20 samples).  I would not suggest using captures of this size as many things can go wrong during a potential capture.  So long term drift measurements are possible, but you really need to isolate the EVM from thermal variants (such as fans, general air currents, etc.) and have a stable PC connection for power.  A transient can cause the communication to halt and all data captured to that point will be lost.

    Best regards,
