Status model

2470-901-01 Rev. A / May 2019 B-25

Using TSP commands:

reset()

-- Clear the reading buffer

defbuffer1.clear()

-- Configure the source and take a measurement

smu.source.range = 1

smu.source.level = 1

smu.source.ilimit.level = 10e-3

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.

trigger.model.setblock(1, trigger.BLOCK_LOG_EVENT, trigger.LOG_INFO1, "Measurement

Started.")

trigger.model.setblock(2, trigger.BLOCK_MEASURE, defbuffer1)

trigger.model.setblock(3, trigger.BLOCK_LOG_EVENT, trigger.LOG_INFO2, "Measurement

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).

status.operation.setmap(0, trigger.LOG_INFO2, trigger.LOG_INFO1)

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

status.operation.enable = 1

-- Enable the Operational Summary Bit to set the Master Summary

-- Bit/RQS

status.request_enable = status.OSB

smu.source.output = smu.ON

trigger.model.initiate()

waitcomplete()

smu.source.output = smu.OFF

printbuffer(1, defbuffer1.n, defbuffer1)
