I am attempting to log the GPS coordinates with the N934CN with recording a .TRC file. The GPS option is installed and working. In the spectrogram mode, I start logging a file (.TRC) mode, and the GPS icon shows a green "G" with the Latitude/Longitude. When I review the spectrogram playback of the file with the Agilent HSA software, the Latitude/Longitude shows "Null." If I save the file as a .CSV, the Lat/Long is logged.
