Sweep Trigger Source
In the sweep mode, the U2761A outputs a single sweep when a trigger signal is
received. After one sweep from the start frequency to the stop frequency, the
U2761A will continuously output the preset waveform at the start frequency while
waiting for the next trigger.
– The sweep trigger source consists of Internal (immediate), External, or Manual
– When the Internal source is selected, the U2761A outputs a continuous sweep
– When the External source is selected, the U2761A accepts a hardware trigger
– When the Manual source is selected, the U2761A outputs one sweep each
