  • Page 30: Test Precautions

    ACCEPTANCE TESTING Test precautions To ensure minimum errors and uncertainties when making measurements, it is important to observe the following precautions: Always use recently calibrated test equipment, with any correction figures taken into • account, so as to establish a known traceable limit of performance uncertainty. This uncertainty must be allowed for in determining the accuracy of measurements.
  • Page 31 Checking that the UUT powers up correctly This test ensures that the 3065 powers up in a satisfactory manner and that the internal self- tests do not report any errors. This test assumes that instrument is fitted in a PXI chassis and that the supplied installation software is installed on the host controller.
