Address Information
— Each device must have its own unique address.
— The network analyzer's default GPIB address in the controller mode is
21.
— The address set on each device must match the one recognized by the
analyzer (and displayed).
Refer to the manual of the peripheral to read or change its address.
Troubleshooting Systems with Controllers
Passing the preceding test indicates that the analyzer's peripheral functions
are operating normally. Therefore, if the analyzer has not been operating
properly with an external controller, check the following:
— The GPIB interface hardware is incorrectly installed or not operational.
(Refer to the embedded help in your analyzer.)
— The programming syntax is incorrect. (Refer to the embedded help in your
analyzer.)

LAN Troubleshooting

Problems with the Local Area Network (LAN) can be difficult to solve. Software
and protocol problems can make it difficult to determine whether the
analyzer's hardware is working properly, or if there is a problem with the LAN or
cabling.
