Triggering
Applies only to bursts and frequency sweep. You can issue triggers for
bursts and sweeps using internal triggering, single triggering, or
external triggering.
• Internal or “automatic” triggering is enabled when you turn on the
function generator. In this mode, the function generator outputs
continuously when the burst mode or sweep mode is selected.
• Single triggering outputs one burst or initiates one sweep each time
you press
Single from the front-panel. Continue pressing this key to
re-trigger the function generator.
• Pressing
Single to enable the single trigger mode also enables the
external trigger mode. External triggering is like the front-panel
single trigger mode except that you apply a trigger signal to the
rear-panel Ext Trig terminal. The function generator is triggered on
the rising edge of a
TTL pulse.
• The
Single key is disabled when in remote (the Rmt annunciator
turns on when in remote) and when a function other than burst or
sweep is selected.
