Checking the SERIAL (RS-232), PARALLEL (1284-C), or VGA Port

To verify the proper operation of the SERIAL, PARALLEL, or VGA port:
• Connect a known good serial, parallel, or VGA peripheral device.
• Wait 15 seconds for the analyzer to verify the device connection, and then check the
operation of the peripheral device.
• If the peripheral device performs correctly, the port is functioning properly.
• If the peripheral device does not function properly, the A15 CPU board is faulty. Refer to
"Removing and Replacing the A15 CPU Board" on page

Checking the GPIB Port

The network analyzer uses a National Instruments 488.2 GPIB controller and associated
driver software. This software includes a test utility which scans the GPIB bus and returns
the status of all the connected peripherals.
To run the test utility software and check the GPIB status:
1. Connect a known good peripheral to the analyzer using a known good GPIB cable.
2. On the menu, point to

9. If problems are detected, check the connections of all GPIB cables, and check all the
GPIB addresses of the instruments on the bus.
NOTE 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.
