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 to "POS" or "NEG".
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.
