ACCEPTANCE TESTING
Introduction
The test procedures in this chapter enable you to verify that the electrical performance of the signal
generator complies with the Performance Data 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.
