Solving GPIB Common Problems

Solving GPIB Common Problems

Problem

Probable Cause

Solution

Unable to communicate

with Broadband Source (no

response from *IDN?

command).

Incorrect communication

type selected.

Select the correct

communication type:

RS-232 or GPIB.

Incorrect communication

parameters.

Check the communication

parameters: bus address,

baud rate, flow control, etc.,

as required.

Incorrect termination

characters.

Synchronize termination

characters between the

GPIB controller and the SCPI

Manager.

Poor bus connection.

Ensure the functioning of

the controller card and

make sure that the bus

cable is properly connected.

Improper configuration.

Verify that the GPIB

interface is properly

configured.

Receive “Undefined

header” error.

Incorrect command syntax. Verify and correct syntax.

Unstable communication.

Incorrect termination

character.

Synchronize termination

characters between the

GPIB controller and the SCPI

Manager.
