Trigger
Selects the trigger source and sets trigger-related parameters.
Trigger Source
Sets "Free Run", "External 1", "External 2", "Power (Time)", or "FMT" to be the
trigger source.
Free Run
The trigger conditions are met at any time, that is, the analyzer generates trigger
signals continuously.
External 1
In this mode, an external signal is input via the [TRIGGER IN] connector on the
rear panel. When the signal meets the set trigger conditions, trigger signals are
generated.
1. Slope
Sets the trigger polarity for External Trigger 1. It is set positive to trigger on a
rising edge and negative to trigger on a falling edge.
2. Delay State
Enables or disables the trigger delay function. After the trigger delay function is
enabled, you can set the trigger delay time.
3. Delay Time
Sets the time interval during which the instrument waits to start the sweep
operation after the trigger signal that meets the trigger conditions is generated.
You can use the numeric keys, the knob, or arrow keys to modify this parameter;
you can also use the touch screen to modify the parameter.
