External Triggering In the external trigger mode, the waveform
generator will accept a hardware trigger applied to the rear-panel
Trig In connector. The waveform generator initiates one sweep or
outputs one burst each time Ext Trig receives a TTL pulse with the
specified edge.

• Front-Panel Operation: The external trigger mode is like the manual
trigger mode except that you apply the trigger to the
