Chapter 3 Features and Functions
Triggering
3
Triggering
Applies to sweep and burst only. You can issue triggers for sweeps or
bursts using
internal
triggering,
external
triggering, or
manual
triggering.
• Internal or “automatic” triggering is enabled when you turn on the
function generator. In this mode, the function generator outputs
continuously when the sweep or burst mode is selected.
• External triggering uses the rear-panel Trig In connector to control
the sweep or burst. The function generator initiates one sweep or
outputs one burst each time Trig In receives a TTL pulse. You can
select whether the function generator triggers on the rising or falling
edge of the external trigger signal.
• Manual triggering initiates one sweep or outputs one burst each time
you press from the front-panel. Continue pressing this key to
re-trigger the function generator.
• The key is disabled when in remote and when a function other
than burst or sweep is currently selected.
Trigger Source Choices
Applies to sweep and burst only. You must specify the source from which
the function generator will accept a trigger.
• Sweep trigger source: Internal, External, or Manual. The default
is Internal.
• The function generator will accept a manual trigger, a hardware
trigger from the rear-panel Trig In connector, or continuously output
sweeps or bursts using an internal trigger. At power-on, internal
trigger is selected.
