Board, System, Time Stamp, and Optional GPS
The lower right section of the window shows the Board identifier, the Sys−
tem identifier, and the Time Stamp. The GPS Longitude, GPS Latitude,
and GPS Altitude will also be displayed if your Talon system has the GPS
option. All of these parameters were stored in the file header when the file
was recorded.
Signal Characteristics
In order for the File Viewer to properly scale signals that are being acquired
by the Talon recorder, it is necessary to provide information about the
acquisition setup.
• In the case of an Analog Talon signal recorder, information about the
setup of the A/D converters and other pertinent information is obtained
by the File Viewer via the data recording's file header to allow for
automatic time and frequency domain signal scaling.
• In the case when real world signals are digitized by an external device
and then sent to and recorded by a Digital Talon signal recorder, you
can still display these signals in the viewer you but must manually set
up the scaling via the GUI.
In order to manually set up the scaling, you must click on the Control switch
shown in

mode, the viewer allows you to input values for the Channel Type, Packing
Mode, Clock, Center Frequency, and Decimation. Setting these to match
your signal acquisition settings will result in the proper scaling in both the
Time and Frequency domain windows. Additionally, the numeric value
displayed in the Frequency detection window should accurately show the
frequency of the primary tone that was acquired.
