Tsp-Link Nodes; Connect The Tsp-Link Cable - Keithley 708B Reference Manual

Section 6: Instrument programming

TSP-Link nodes

Uniquely identify each instrument or enclosure attached to the TSP-Link bus. Identify each instrument
using a TSP-Link node number, and each enclosure using a node. Each node must be assigned a
unique node number.
In test script programs, nodes look like tables. There is one global table named node that contains all
the actual nodes that are themselves tables. An individual node is accessed as node[N] where N is
the node number assigned to the node. Each node has certain attributes that can be accessed as
elements of its associated table. These are listed as follows:
•
model: The product model number string of the node.
•
revision: The product revision string of the node.
•
serialno: The product serial number string of the node.
There is also an entry for each logical instrument on the node (see
3)).
It is not necessary to know the node number of the node running a script. The variable localnode is
an alias for the node entry the script is running on. For example, if a script is running on node 5, the
global variable localnode will be an alias for node[5].

Connect the TSP-Link cable

Connect the TSP-Link connector to one of the TSP-Link connectors on the rear panel of the
instrument.
The location of the TSP-Link connectors on the instrument are shown below.
For an example of setting up a TSP-Linked system, see "Working with a Series 2600A" in the Models
707B and 708B User's Manual.
