The defaults of respective parameters are as follows:

Sweep stop signal level: 3

Sweep stop time:	2 sec
Sweep width:	100 kHz
Step frequency:	1 kHz

These can be adjusted on system codes 9951 through 9954.

Note: Sweep width is the frequency width to sweep on both sides of the selected frequency. Sweep step is the frequency interval at which the receiver sweeps the sweep width.
