Save and Export Results

Save Results

There are two quick options to save your results and settings file.

  • Click Save to save the changes made in the instrument settings and raw data of the loaded file.
  • Click Save As to save the settings and raw data in a new .analysis file with the filename of your choice.

When handling a large data set, the time taken for the software to save your results may vary depending on the size of your file and your PC specifications.

NOTE

Depending on the mode selected in Triggersprior running the measurement, the software will create the following files. You will need these files to successfully load and retrieve your offline data onto the Event-Based Power Analysis software.

For Single or Triggered Mode:

  • .Analysis2 files contain the software settings, raw data and the re-sampled data. This is the file users will create when they first launch the Event-Based Power Analysis software.

For Continuous Mode:

  • .Analysis2 files contain the software settings and the re-sampled data.
  • .H5 files is created when the Continuous Mode is selected in the Triggers setting. This file will contain the raw data recorded using the continuous mode.

Export Results

It is recommended to use the Export function to capture a snapshot of the analysis at different zoom levels. Exporting your data to a CSV file will include the following information:

  • Main chart will export up to 3000pts (current zoom level of the main chart)
  • CCDF Chart Data
  • Occupied Time/Consumption Chat Data
  • Summary information (battery life, total charge, cycle time, max current, average current) for data range of main chart
  • Configuration information

This function will not export the full data set in a .csv file.

Before you export your data, ensure that your results are up-to-date. Click File > Export and browse to the location to save the .csv file.


IMPORTANT

Application Limitations

However, exporting a full data set to CSV may not be practical due to the size of the datasets and its dependency on the actual computing platform. The CSV file format becomes increasingly more difficult to use since they require the whole data set to be loaded into RAM (at least temporarily). The Hierarchical Data Format, Version 5, (HDF5) is a better way.

Software Package Limitations:

  • Excel: Approximately a million rows
  • Minitab: Approximately 10 million rows
  • SAS: Approximately two billion rows
  • Mathematica: Likely similar to Matlab but limited by system resources
  • Matlab: Approximately 2^45 rows (3.5E13)

HDF5 or H5 File Format

The Hierarchical Data Format, Version 5, (HDF5 or H5) is a general-purpose, machine-independent standard way used by engineering and scientific fields to store scientific data in files so that it can be shared. Since this file format is more efficient than a CSV file, a lot of software packages are already supporting this file format.

For Continuous Mode data, the Event-based Power Analysis software will store the data in HDF5 or H5 files format. As such, you can directly import this file type into most of the applications such as SAS, Mathematica, and Matlab. Those that do not have the native support may require a plug-in to do so.
