-- Configure the source and take a measurement

smu.measure.range = 10e-3
-- Setup the NPLC for a really long measurement
smu.measure.nplc = 10
-- Use the trigger model to create events before and after
-- the measurement to generate SRQ when measurement is done.

Done.")
-- Clear the status byte
status.clear()
-- Map bit 0 of the Operation Event Register to set on the Measurement
-- Done log notification (trigger.LOG_INFO2) and clear on the
-- Measurement Started log notification (trigger.LOG_INFO1).

-- Enable bit 0 to flow through to the status byte.
