  • Question

  • A test system using the GPIB is being used to monitor a potentially dangerous crash test from a distance of 200 feet. The engineer decides to have you fabricate a special cable, rather than order one, since all the materials are on hand and the tests are already behind schedule. When the tests are run, the test system is erratic and the data is almost useless. What has gone wrong?


  • Options
  • A. The engineer is probably not using the correct data format for the specific instruments being used to collect the data.
  • B. The GPIB cable is too long; a bus extender should be used.
  • C. The cable should be shielded and properly grounded.
  • D. The tests themselves probably produced extraneous signals that confused the instruments, resulting in unusable data.

  • Correct Answer
  • The GPIB cable is too long; a bus extender should be used.
