Usage
trigger.model.setblock(
blockNumber
, trigger.BLOCK_MEASURE)
trigger.model.setblock(
blockNumber
, trigger.BLOCK_MEASURE,
bufferName
)
trigger.model.setblock(
blockNumber
, trigger.BLOCK_MEASURE,
bufferName
,
count
)
blockNumber
The sequence of the block in the trigger model
bufferName
The name of the buffer, which must be an existing buffer; if no buffer is defined,
defbuffer1
is used
count
The number of measure readings to make before moving to the next block in the
trigger model; set to a specific value or infinite (
trigger.COUNT_INFINITE
) or
stop infinite (
trigger.COUNT_STOP
)
Details
When trigger model execution reaches this block:
1.
The instrument begins making a measurement.
2.
The trigger model execution waits for the measurement to be made.
3.
The instrument processes the reading and places it into the specified reading buffer.
When you set the count to a finite value, trigger model execution remains at the block until all
operations are complete. If you set the count to infinite, the trigger model executes subsequent blocks
and measurements continue in the background until the trigger model execution reaches another
measure block, a wait block, or until the trigger model ends.
You must select a measure function before running a trigger model that contains this block.
If you are using a user-defined reading buffer, you must create it before you define this block.
Example
reset()
smu.measure.func = smu.FUNC_DC_VOLTAGE
trigger.model.setblock(1, trigger.BLOCK_BUFFER_CLEAR, defbuffer1)
trigger.model.setblock(2, trigger.BLOCK_DELAY_CONSTANT, 0)
trigger.model.setblock(3, trigger.BLOCK_MEASURE, defbuffer1,
trigger.COUNT_INFINITE)
trigger.model.setblock(4, trigger.BLOCK_WAIT, trigger.EVENT_DISPLAY)
trigger.model.setblock(5, trigger.BLOCK_MEASURE, defbuffer1, trigger.COUNT_STOP)
trigger.model.setblock(6, trigger.BLOCK_NOTIFY, trigger.EVENT_NOTIFY1)
trigger.model.initiate()
waitcomplete()
print(defbuffer1.n)
