Rear Panel Troubleshooting
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 7-28
.
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
System
menu, point to
Configure,
and then click
SCPI/GPIB
.
A
SCPI/GPIB
dialog
box is displayed.
3. In the
GPIB
block, click
System Controller
to establish the analyzer as a controller. Wait
for the analyzer to configure, and then click
OK
.
4. On the
System
menu, click
Windows Taskbar
to
open the
Start Menu
window.
5. On the
Start Menu
window, point to
Programs, National Instruments NI-488.2,

6. On the left side of the
Measurement & Automation
window under folders:
a. Click the plus sign to expand the
Measurement & Automation
folder.
b. Click the plus sign to expand the
Devices and Interfaces
folder.
c. Right click
GPIB0 (AT-GPIB/TNT)
to open a submenu.
7. On the submenu, click
Scan for Instruments
to run the test.
8. The state of all the peripherals found on the bus is returned.
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.
