Data Logging

Touchstone -- Logging Mode

Data Logging
This mode allows recording of spectrum trace data (in CSV format) for extended periods. To begin logging press the ‘Start’ button — which will first prompt for a filename to save the CSV-formatted spectrum trace data, and then scanning will begin. When you are finished, logging ends when you press the ‘Stop’ button. As the logging progresses it is displayed in the form of a waterfall / heatmap that gradually scrolls upward with each scan.

Included in the installation folder is an example of a VBA macro for viewing the CSV data as a heatmap in Microsoft Excel. Here’s a link that explains more about this very useful feature: Excel Heatmap

NOTE: The heatmap created above by Touchstone-Pro and the one below created by Excel use the same data but different color scales.
