GPIB Hardware Checks

This section gives guidelines to make hardware troubleshooting checks

for the GPIB card (such as an Agilent 82351 PCIe™-GPIB), including:

• Check Cables/Connections/Power.

• Check Device Manager

• If Sound Card Does Not Work

• If Data Transfers to Devices Fail

• If Connection Expert Finds an Agilent 82350 Card with Serial

Number ffffffff

Check Cables/Connections/Power. Start your troubleshooting

sequence by performing the following hardware checks. If the hardware

checks do not solve the problem, see GPIB Software Checks.

Check GPIB Cable Connections. Check all GPIB cables for good

connection to the GPIB connector on the interface card installed in

your PC and the GPIB cable connections between all connected

GPIB instruments. An improperly attached GPIB connector can

cause the bus to malfunction.

Check GPIB Cables for Damage. Check all GPIB cables for

cuts/damage and check for bent/misaligned/crushed connector pins.

Replace cables as required.

Disconnect/Reconnect GPIB Cables. If Steps 1 and 2 do not solve the

problem, try disconnecting and reconnecting (or replacing) GPIB

cables.

Check PC/Instrument Power-on. Verify that the PC and all connected

GPIB instruments are functional and are powered ON. Verify that

host computer is not in a Suspended power management state.

Reboot Your PC. If doing Steps 1, 2, 3 or 4 does not solve the

problem, reboot the PC. If this does not solve the problem, go to

Check Device Manager.

NOTE

There are no user-serviceable parts for the GPIB Interface cards. If you

suspect a hardware failure for interface card, contact Agilent for

instructions to replace or repair the unit. See Contacting Agilent for
