Figure 29: GPIB and DB-9 cable connections for the SCPI programming example
The figure above also shows the communication cabling if you are using the GPIB remote
communication interface. GPIB cable #1 connects the GPIB port on the computer (controller) to the
IEEE-488 connector on the rear panel of Model 2450 #1. GPIB cable #2 is connected between the
IEEE-488 connectors of the two Model 2450s.
Each Model 2450 must have a different GPIB address. You can set this up using the front panel. For
details, see
(on page 3-3).
If you are connecting the computer and Model 2450 instruments using USB cables, each instrument
must be connected to the computer with a separate USB cable.
If you are connecting the computer and Model 2450 instruments using an ethernet connection, the
instruments and computer must be connected using an ethernet switch or hub.
Connections for the TSP command set
If you use the Test Script Processor (TSP
®
) command set for remote programming, use a Model
CA-180-3A crossover cable (one is included with the Model 2450) to connect the TSP-LINK ports on
the rear panels of the Model 2450 instruments to each other (see figure below). For more information
about using TSP-Link, see "TSP-Link System Expansion Interface" in the Model 2450 Reference
Manual.
