Importing Traces

Both the Spectrum Trace and Smart Trace modes support importing a spectrum trace to be used during intermodulation analysis.  Two formats are supported.  The first follows the format used by Pro Audio White Space Finder (PAWS4400) to export spectrum traces -- the format of the XML file must obey the following schema: 

<?xml version="1.0" encoding="us-ascii"?>

And the second format uses comma-separated [frequency (MHz), amplitude (dBm)] pairs, similar to that shown below.  The data exported by the Thurlby Thandar Instruments (TTI) PSA series hand-held spectrum analyzer is already in the correct format.
