TSP-Link System Expansion Interface
Keithley Instruments TSP-Link
®
is a high-speed trigger synchronization and communication bus that
test system builders can use to connect multiple instruments in a master and subordinate
configuration. Once connected, all the instruments that are equipped with TSP-Link in a system can
be programmed and operated under the control of the master instrument or instruments. The test
system can have multiple master and subordinate groups, which can be used to handle multi-device
testing in parallel. Combining TSP-Link with a flexible programmable trigger model ensures speed
and accuracy.
Using TSP-Link, multiple instruments are connected and can be used as if they are part of the same
physical unit for simultaneous multi-channel testing. The test system can be expanded to include up
to 32 TSP-Link-enabled instruments.
TSP-Link functionality is only available when using the instrument front panel or the TSP commands
to control the instrument. It is not available if you are using SCPI commands.
TSP-Link connections
The Model 2450 has three synchronization lines that are built into the TSP-Link connection. If you are
using a TSP-Link network, you do not have to modify any connections.
Example connections for a TSP-Link system are shown in the following figure.
The TSP-Link connectors are on the rear panel of the instruments. All the instruments in the system
are connected in a sequence (daisy-chained) using LAN crossover cables.
