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: The input signal frequency on the external trigger interface should not be 
greater than 1 MHz.
1.  Slope 
Sets the trigger polarity for External Trigger 2. 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.

: A negative trigger delay time indicates a pre-trigger. 
Power (Time) 
A trigger signal will be generated when the system detects that the IF signal power 
exceeds the set IF power. 
1.  Delay State 
Enables or disables the trigger delay function. After the trigger delay function is 
enabled, you can set the trigger delay time.
