· [Free Trigger]: When the previous single or continuous sweep finishes,
the next sweep or measurement is automatically triggered.
· [Video Trigger]: Set the trigger mode as [Video]. Once the input signal
exceeds the set video triggering level sweeping will be triggered. The trigger
level value can be set by the number keys, stepping keys or knob. The green
line on the screen indicates the selected trigger level.
· [External triggering]: Enable the [External] mode. Set the triggering level
and synchronize “Sweep” or “Measure” with next voltage cycle.
· [Trigger Polarity]: Control the positive or negative polarity of level
triggering. The rising edge will be applied for triggering in the case of
positive polarity, and falling edge in the case of negative polarity.
· [Trigger delayed]: The level triggering delay can be set. In this case, the
spectrum analyzer will wait for the delay time after receiving the external
trigger signal and before sweeping.
