HP 33120A User Manual

Single Triggering In the single trigger mode (front panel only),
you can manually trigger the function generator by pressing the
front-panel
Single key. The function generator outputs one burst or
initiates one sweep each time you press the key. The
Trig
annunciator turns on when the function generator is waiting for
a single trigger.
The front-panel
Single key is disabled when in remote.
External Triggering In this trigger mode, the function generator will
accept a hardware trigger applied to the Ext Trig terminal. The function
generator outputs one burst or initiates one sweep each time Ext Trig
receives the rising edge of a
TTL pulse.
See also “Ext Trig/FSK/Burst Input Terminal,” on page 102.
• Front-Panel Operation: The external trigger mode is like the single
trigger mode except that you apply the trigger to the Ext Trig
terminal. Pressing
Single to enable the single trigger mode also
enables the external trigger mode. The
Trig annunciator turns on
when the function generator is waiting for an external trigger.
The front-panel
Single key is disabled when in remote.
