Remote communications interfaces
You can choose from one of several communication interfaces to send commands to and receive
responses from the 2450.
You can control the 2450 from only one communications interface at a time. The first interface on
which the instrument receives a message takes control of the instrument. If another interface sends a
message, that interface can take control of the instrument. You may need to enter a password to
change the interface, depending on the setting of interface access.
The 2450 automatically detects the type of communications interface (LAN, USB, or GPIB) when you
connect to the respective port on the rear panel of the instrument. In most cases, you do not need to
configure anything on the instrument. In addition, you do not need to reboot if you change the type of
interface that is connected.
Supported remote interfaces
The 2450 supports the following remote interfaces:
• GPIB: IEEE-488 instrumentation general purpose interface bus
• Ethernet: Local-area-network communications
• USB: Type B USB port
• TSP-Link: A high-speed trigger synchronization and communications bus that test system
builders can use to connect multiple instruments in a master-and-subordinate configuration
For details about TSP-Link, see “TSP-Link System Expansion Interface” in the Model 2450 Reference
Manual.
