Tips and Options to Capture and View Data with a Beagle Protocol Analyzer

Question from the Customer:

I have a project where I need to compare the temperatures of two separate devices in the same environment.  I’m looking to use the Beagle I2C/SPI Protocol Analyzer to collect and plot the data. How can I best capture and view the data?

Response from Technical Support:

Thank you for your questions!  You can easily capture and view data using the Beagle I2C/SPI Protocol Analyzer with our Data Center Software. This solution offers you two ways to save and view the data: one is viewing the .tdc log file that the Data Center Software saves; another method is exporting the data in .csv format and viewing the data in an Excel sheet (or other tool).

NOTE – Saving and viewing data like this works for all models of Total Phase Beagle analyzers.

  • Method 1. Use the Beagle analyzer with the Data Center software, and save the transaction log as a .tdc file. Then you can use the Data Center Software to open and view the .tdc file. For more information, please refer to sections Saving a Capture  and Save Settings of the Data Center Software User Manual. You will need two instances of Data Center Software to view two separate data files.
  • Method 2. You can use Beagle analyzer and Data Center Software to export the transaction log to .csv or bin format. Then you can use Microsoft Office Excel (or another tool that is compatible with .csv or bin formats) to open the .csv or bin file. You could then use the plotting and graphing tools in Microsoft Office Excel to plot your data.  For additional information, please refer to section Exporting a Capture of the Data Center Software User Manual.

When you export data, to make sure you save complete data records, do the following with the Data Center Software:

  1. Click File
  2. Click Export
  3. Enter file name in the File Name text box
  4. Click Save
  5. Disable Export Only Visible Records
  6. Click OK
