- Of particular interest to many users will be the CPU load (excessive CPU load may cause sluggish behaviour or freezing of the computer), and Audio latency. Apart from DDC bandwidth, CPU load may be minimized by reducing the Demodulator filter length (...
- Note: When measuring sensitivity using SINAD, it is very important that the Audio Filter is enabled and the cut-off frequencies (and for FM measurements, also the de-emphasis) are set according to the specified test conditions. Proper audio filtering ...

The user needs to select a memory group within which the scan will be
performed (note that particular frequencies in the group can be “locked out” –
refer to the chapter Memory under Function tabs). The scan can be
performed in either direction using either the left
or right arrow
buttons. The scan can be stopped using the Stop button
or paused
using the Pause
button.
Using the Options button, one can specify the scanners behavior when a
signal is found: The scanner can either pause for a predetermined amount of
time (waiting for a signal to reappear) or simply stop scanning.
Additional conditions are available to choose from, that define when the
scanner should resume scanning, such as when the signal disappears, after a
certain delay time, etc.
Logger
The Excelsior receiver is equipped with a simple logging function that makes it
possible to log signal strength on up to two frequencies at the same time.
These are specified by simply tuning one or both of the two receivers (RX1 or
RX2) to the desired frequencies.
