TSP-Net
Overview
The TSP-Net
®
library allows the Model 2657A to control LAN-enabled devices directly through its LAN
port. This enables the Model 2657A to communicate directly with a device that is not TSP
®
enabled
without the use of a controlling computer.
TSP-Net compared to TSP-Link to communicate with TSP-enabled
devices
The TSP-Link
®
network interface is the preferred communication method for most applications where
communication occurs between the Model 2657A and another TSP-enabled instrument.
One of the advantages of using the TSP-Link network interface is that TSP-Link connections have
three synchronization lines that are available to each device on the TSP-Link network. You can use
any one of the synchronization lines to perform hardware triggering between devices on the TSP-Link
network. Refer to
(on page 3-55) for details.
However, if the distance between the Model 2657A and the TSP-enabled device is longer than
15 feet, use TSP-Net commands.
TSP-Net capabilities
The TSP-Net library permits the Model 2657A to control a remote instrument through the LAN port for
both Test Script Processor (TSP
®
) and non-TSP instruments. Using TSP-Net library methods, you
can transfer string data to and from a remote instrument, transfer and format data into Lua variables,
and clear input buffers. The TSP-Net library is only accessible using commands from a remote
command interface, and is not available from the front panel.
You can use TSP-Net commands to communicate with any ethernet-enabled instrument. However,
specific TSP-Net commands exist for TSP-enabled instruments to allow for support of features unique
to the TSP scripting engine. These features include script downloads, reading buffer access, wait
completion, and handling of TSP scripting engine prompts.
Using TSP-Net commands with TSP-enabled instruments, a Model 2657A can download a script to
another TSP-enabled instrument and have both instruments run scripts independently. The Model
2657A can read the data from the remote instrument and either manipulate the data or send the data
to a different remote instrument on the LAN. You can simultaneously connect to a maximum of
32 devices using standard TCP/IP networking techniques through the LAN port of the Model 2657A.
