Dataqueue.capacity - Keithley 3700A Series Reference Manual

Series 3700A System Switch/Multimeter Reference Manual
Details
You cannot use the timeout value when accessing the data queue from a remote node (you can
only use the timeout value while adding data to the local data queue).
The timeout value is ignored if the data queue is not full.
The dataqueue.add() function returns false:
▪
If the timeout expires before space is available in the data queue
▪
If the data queue is full and a timeout value is not specified
If the value is a table, a duplicate of the table and any subtables is made. The duplicate table does
not contain any references to the original table or to any subtables.
Example
dataqueue.clear()
dataqueue.add(10)
dataqueue.add(11, 2)
result = dataqueue.add(12, 3)
if result == false then
print("Failed to add 12 to the dataqueue")
end
print("The dataqueue contains:")
while dataqueue.count > 0 do
print(dataqueue.next())
end
