Operating Modes

Continuous

Output  continuous at programmed parameters

Triggered

Output  quiescent until triggered by an internal or external trigger,

at which time one waveform cycle is generated to programmed

parameters. Frequency of waveform cycle is limited to 1 MHz.

Gate

-

Same as triggered mode, except

waveform is executed for the

duration of the gate signal.

The last cycle started is

completed.
