Trigger control and sweeping both happen on the radio frequency
connector. Once a sweep is done, it will be displayed until a trigger condition
occurs again and it performs another sweep. This is used in zero-span mode.
In order to use this function, the trigger condition needs to be set up:
1.
Monitor the RF data to determine the trigger condition.
2. Set the power level at center freq.
3. Set the trigger level:

High Level - Trigger if dBm rises ABOVE the power level.

Low Level - Trigger if dBm falls BELOW the power level.
4. Enable the trigger.
