Record Playback

Record Playback allows you to record SA trace sweeps and play them back at a later
time. Use this feature to monitor spectrum activity over a period of time.
You can record traces continuously, record a specified number of traces (segments),
or record when triggered by a specified power level.
Traces can be recorded from, or played back into, any measurement type (such as
Channel Power or Occupied BW) or any display type (such as Spectrogram and
Waterfall).
When GPS is enabled and displayed, the current location and elevation are saved
and played back with traces.
Recordings can be saved to the FieldFox Internal memory, an SD Card, or a USB
flash drive.

About Sessions

A Recording Session is a collection of recorded traces and the instrument states that
generated them.
Before recording can occur, a new session must be initiated or an existing session
must be opened. Sessions can later be opened for playing or continued recording.
Only one session can be open at a time.
You close the session when finished recording or playing. A session is also closed
when the FieldFox is Preset (or Mode Preset), an Instrument State is recalled, or
when Mode is changed from SA.
Each session is saved as a folder containing a set of files on the specified storage
device.
How long can a recording session last?
There are many variables that determine the possible length of a recording session.
But one key variable is the amount of available memory.
