Trigger modes

Triggering can be done in frequency domain (e.g. scanning a certain span) or in time domain (e.g. with zero span). Triggering in frequency domain can be slow due to the time required to scan the frequency span.

  • AUTO is the normal spectrum analyzer scanning mode, triggering is not active.
  • NORMAL will display a new scan as soon as a signal in the scan causes a trigger event.
  • SINGLE will wait for a signal to cause a trigger event and display the scan. Restart the waiting for an event by activating SINGLE again.
  • LEVEL activates a keypad for entering the trigger level. The specified trigger level will be shown in the status panel and as a blue line
  • UP EDGE generates a trigger event when the input level goes from below the set trigger level to above the set trigger level
  • DOWN EDGE generates a trigger event when the input level goes from above the set trigger level to below the set trigger level
  • BACK returns to the Level menu

The active trigger level is shown on the screen as a blue line and in the status at the left. The trigger level in the status is shown in red when waiting for the trigger to happen and in green when a single trigger happened
