Delta Trace View

The Delta Trace view can be used to view small (or large) changes in the RF spectrum over time.

When scanning begins, the first trace is saved as a snapshot. For all subsequent scans, the snapshot trace is subtracted from the current trace and the difference, i.e. 'delta', is displayed.  Plotting the data in this way makes it easy to detect RF changes in transmitted signals that occurred since the initial snapshot and is most useful in environments where RF transmissions change over time.
