Details
If the data queue is empty, the function waits up to the timeout value.
If data is not available in the data queue before the timeout expires, the return value is nil.
The entries in the data queue are removed in first-in, first-out (FIFO) order.
If the value is a table, a duplicate of the original table and any subtables is made. The duplicate table
does not contain any references to the original table or to any subtables.
Example
for i = 1, 10 do
dataqueue.add(i)
end
print("There are " .. dataqueue.count
.. " items in the data queue")
while dataqueue.count > 0 do
x = dataqueue.next()
print(x)
end
print("There are " .. dataqueue.count
.. " items in the data queue")
Clears the data queue, adds ten entries, then
reads the entries from the data queue. Note that
your output may differ depending on the setting
of format.asciiprecision.
Output:
There are 10 items in the data queue
1.0000000e+00
2.0000000e+00
3.0000000e+00
4.0000000e+00
5.0000000e+00

delay()
This function delays the execution of the commands that follow it.
Type TSP-Link accessible
Affected by Where saved Default value
Function No
Usage
delay(seconds)
The number of seconds to delay (0 to 100 ks)
Details
The instrument delays execution of the commands for at least the specified number of seconds and
fractional seconds. However, the processing time may cause the instrument to delay 5 μs to 10 μs
(typical) more than the requested delay.
