When first selected, the Average Peak option will temporarily display a slider bar to custom set the
number of traces to be averaged. (The range option is 2-64 with a default of 16.) Move the slider bar to
select the desired number. The bar will disappear after a few seconds.
Persistence Trace
This option toggles the display of the persistence trace. The persistence trace displays the trace data
from each sweep of the receiver using fading colors to indicate how frequently and recently each signal
was encountered. Transient signals are displayed in darker colors (blues & greens) and fade quickly,
whereas more permanent or persistent signals are displayed in brighter colors (reds and yellows). This
enables the user to easily identify transmit signals even when surrounded by multiple transient signals
or noise.
Note: The Persistence Trace option is only available in the Mode Settings Menu at spans of 200 MHz and
below.
Note: The persistence trace update rate will begin to get noticeably slower at spans less than 500 kHz.
This is normal. This is because a longer dwell time is necessary at smaller spans to perform the
acquisitions needed for the persistence trace display.
