Details
The source building block determines if the output source is turned on or off when the trigger model reaches this
block.
This block does not determine the settings of the output source (such as the output voltage level and source
delay). The source settings are determined by either the present settings of the instrument or by a source
configuration list.
When you list trigger blocks, this block is listed as SOURCE_OUTPUT.
Example
trigger.model.setblock(2, trigger.BLOCK_SOURCE_OUTPUT, 1)
Set trigger model to turn the source on when it reaches block 2.
