Pulse configuration options

Use stdysel to select what value is output continuously by the signal generator after the generation of a pulse.

• 0: the last calculated sample of the pulse

• 1: a zero value

Use mode to select whether the output is periodic or one-shot. Here is what happens after generating the specified number of samples. Look in the queue to see if there is a new waveform to generate. If there is a new waveform in the queue, remove it from the queue and generate it. If there is not, use the value of mode to decide what to do.

• 0: stop

• 1: repeat the current waveform

Then continue looking for a new waveform.

Use outsel to select the output source. The output is complex. Tables define envelopes for I and Q.

• 0: product of table and DDS

• 1: DDS

• 2: from the table for the real part, and zeros for the imaginary part

• 3: always zero
