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:
z High Level - Trigger if dBm rises ABOVE the power level.
z Low Level - Trigger if dBm falls BELOW the power level.
z Pwr Level - Set the power level using the keypad.
4. Enable the trigger.
