Gated

Same as Triggered mode except that the waveform is generated for as long as the gate signal stays true (logic one). When the gate signal goes false (logic zero) the output goes quiescent.

Burst

Output waveform will become active on the occurrence of a trigger edge. The selected waveform is generated for a preset number of cycles between 1 and 999,999. Output will then disable.
