Single pulse example code
Even though no measurements are made in this example, a measure range is set. When sourcing
voltage, it is good practice to set the current measure range equal to the triggered source limit range.
This is especially important when the triggered limit is greater than 100 mA. If the measure range is
not set, it may affect the shape of the pulse. This step is not necessary when sourcing current.

-- Generate a single pulse with the following characteristics:
-- * Bias (idle) level = 0 V
-- * Pulse level = 5 V
-- * Pulse width = 500 us
-- Configure the source function.

-- Set the voltage source range and the idle or bias source level and limit.
