External Triggering In the external trigger mode, the function
generator will accept a hardware trigger applied to the rear-panel
Trig In connector. The function generator initiates one sweep or outputs
one burst each time Trig In receives a TTL pulse with the specified edge.
See also “Trigger Input Signal” on the following page.
• Front-Panel Operation: The external trigger mode is like the manual
trigger mode except that you apply the trigger to the
Trig In
connector
.
To select the external source, press the Trigger Setup softkey and
then select the Source Ext softkey.
To specify whether the function generator triggers on the rising or
falling edge, press the Trigger Setup softkey and then select the
desired edge by pressing the Slope softkey.
• Remote Interface Operation:
TRIGger:SOURce EXTernal
Use the following command to specify whether the function generator
triggers on the rising or falling edge.
TRIGger:SLOPe {POSitive|NEGative}
Manual Triggering In the manual trigger mode (front panel only),
you can manually trigger the function generator by pressing the front-
panel key. The function generator initiates one sweep or outputs
one burst for each time you press the key. The key is illuminated
while the function generator is waiting for a manual trigger (the key is
disabled when in remote).
