System behavior
Using the reset () command
While most TSP-Link
affects the system as a whole by resetting all nodes to their default settings:
-- Resets all nodes in a TSP-Link system.
reset()
node[N] and localnode can be used with reset() to reset only one of the nodes. The other
nodes are not affected. The following programming example illustrates this type of reset operation.
-- Resets node 1 only.
node[1].reset()
-- Resets node 1 only.
localnode.reset()
-- Resets node 4 only.
node[4].reset()
Abort
An abort command will terminate an executing script and return all nodes to local operation (REM
indicators turn off), dissolving the master/subordinate relationships between nodes. An abort
operation is invoked by either issuing an abort command to the master node or pressing the EXIT
(LOCAL) key on any node in the system.
An abort operation can also be performed by pressing the OUTPUT ON/OFF control on any node.
The results are the same as above, with the addition that all source-measure unit (SMU) outputs in
the system are turned off.
Triggering with TSP-Link
The TSP-Link
I/O synchronization lines. See

TSP advanced features

Use the Test Script Processor (TSP
simultaneously, to manage resources allocated to test scripts running in simultaneously, and to use
the data queue to facilitate real-time communication between nodes on the TSP-Link
Running test scripts simultaneously improves functional testing, provides higher throughput, and
expands system flexibility.
There are two methods you can use to run test scripts simultaneously:
•
Create multiple TSP-Link networks
•
Use a single TSP-Link network with groups
The following figure displays the first method, which consists of multiple TSP-Link networks. Each
TSP-Link network has a master node and a GPIB connection to the computer.
