Operating Modes

Continuous - Output continuous at programmed waveshape, frequency, amplitude and offset.

Triggered - Output quiescent until triggered by an external, GPIB or manual trigger; then generates a sequence only one time.

Gated - Same as triggered mode except period is executed only for the duration of the gated signal until the sequence started is completed.

Burst - Output quiescent until triggered by an external, GPIB or manual trigger; then generates "n" sequences or cycles.

Waveform Advance - Continuously generates the waveform in a predefined sequence; the next trigger advances to the next waveform in sequence.

Autostep - Generates the predefined waveform once in the Autostep File; the next trigger advances the waveform.
