Trigger
Selects the trigger source and sets trigger-related parameters.
Trigger Source
Sets "Free Run", "External 1", "External 2", or "Video" to be the trigger source.
1. Free Run
The trigger conditions are met at any time, that is, the analyzer generates
trigger signals continuously.
2. 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.
3. External 2
Press Input Output  Ext Trigger2 to select "In". Then, an external signal is
input via the [TRIGGER IN/OUT] connector on the rear panel. When the
signal meets the set trigger conditions, trigger signals are generated.
Note: For the external trigger interface, the input signal frequency shall not
exceed 1 MHz.
4. Video
A trigger signal will be generated when the system detects a video signal whose
voltage exceeds the specified video trigger level.
Note: This trigger type is available in either of the following conditions:
1) in non-zero span mode
2) when "Average(RMS)" or "Average(Vol)" is selected for the detector
type.
Slope
Sets the trigger polarity for External Trigger. It is set positive to trigger on a rising
edge and negative to trigger on a falling edge.
Trigger Delay Switch
Enables or disables the trigger delay function. After the trigger delay function is
enabled, you can set the trigger delay time.
