However, the Record Options tab allows the user to save information in .csv format for
analysis in other applications.The default format is .amt although .csv can also be selected to
view the data in a spreadsheet format. The captured data can be viewed from both a Spectrum
Analyzer adapter and a WiFi adapter.
