ACCEPTANCE TESTING
46882/439 7-3
Introduction
The test procedures in this chapter enable you to verify that the electrical performance of the
signal generator complies with the specifications given in Chapter 1. For convenience, the test
equipment and specification for each test are summarized before the test procedure.
Apart from the UUT, (Unit Under Test), no specific set-up procedures will be included for the test
equipment unless the measurement is dependent on specific instrument settings or special
measurement techniques.
Test precautions
To ensure minimum errors and uncertainties when making measurements, it is important to
observe the following precautions:
(1) 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.
(2) A common external frequency standard, with an accuracy of ±1 part in 10
9
should be used for
any frequency-controlled test equipment.
(3) Use the shortest possible connecting leads.
(4) Some areas of the specification which are labeled ‘typical’ rather than having clearly defined
limits are not tested.
