RUN MODES
Continuous:
A selected output function shape is output continuously.
Self Armed:
No start commands are required to generate waveforms.
Armed:
The output dwells on a DC level and waits for an enable command and then the output waveform is output continuously; An abort command turns off the waveform.
Triggered:
A trigger signal activates a single-shot or counted burst of output waveforms and then the instrument waits for the next trigger signal.
Normal Mode:
The first trigger signal activates the output; consecutive triggers are ignored for the duration of the output waveform.
Override Mode:
The first trigger signal activates the output; consecutive triggers restart the output waveform regardless if the current waveform has been completed or not.
Gated:
A waveform is output when a gate signal is asserted. The waveform is repeated until the gate signal is de-asserted. Last period is always completed.
Burst:
Upon trigger, outputs a Dual or multiple pre-programmed number of waveform cycles from 1 through 1M.
