Sweep Trigger Source
In sweep mode, the instrument outputs a single sweep when a trigger signal is received. After one sweep from the
start frequency to the stop frequency, the instrument waits for the next trigger while outputting the start frequency.
l Sweep trigger source: Internal (default), External, Time, or Manual.
l With the Internal (immediate) source, the instrument outputs a continuous sweep at a rate determined by the
total of the hold time, sweep time and return time. The sweep time for this source is limited to 8000 seconds.
l With the External source, the instrument accepts a hardware trigger on the rear-panel Ext Trig connector and ini-
tiates one sweep each time Ext Trig receives a TTL pulse with the specified polarity.
l The trigger period must be greater than or equal to the specified sweep time.
l With the Manual source, the instrument outputs one sweep each time the front-panel Trigger key is pressed.
