dataqueue functions and attributes

Use the dataqueue commands to:
•
Share data between test scripts running in parallel
•
Access data from a remote group or a local node on a TSP-Link network at any time
The data queue in the Test Script Processor is first-in, first-out (FIFO).
You can access data from the data queue even if a remote group or a node has overlapped
operations in process.
dataqueue.add()
dataqueue.CAPACITY
dataqueue.clear()
dataqueue.count
dataqueue.next()

delay function

This function is used to hold up instrument operation for a specified period of time. It is typically used
to soak a device at a specific voltage or current for a period of time.
delay() (on page 7-55)

digio functions and attributes

The digital I/O port of the Model 707B or 708B can control external circuitry (such as a component
handler for binning operations). The I/O port has 14 lines. Each line can be at TTL logic state 1 (high)
or 0 (low). See the pinout in
There are commands to read and write to each individual bit, and commands to read and write to the
entire port. Use the following code fragment to write to one bit of the digital I/O port. The I/O bit is then
read and the state is returned to the computer, where it can be processed or displayed.
