Background
Trace options determine how the trace data is
stored or manipulated before being displayed.
The Spectrum Analyzer updates the trace
according to the type of trace.
Definitions
Normal: the Spectrum Analyzer continuously
updates the display with each sweep.
Max/Min Hold: the maximum/minimum points
are maintained for the selected trace. The trace
points are updated each sweep if a new
maximum/minimum point is found.
Average: this mode averages the trace for a user-
defined number of times before it is displayed.
This type of trace smooths the noise level, but it is
slower to update.
