PERFORMANCE TESTS<br />
INTRODUCTION<br />
NECESSARY EQUIPMENT<br />
The procedures in this section test the performance of the <strong>DS335</strong>. The first<br />
set tests the basic functionality of the <strong>DS335</strong> from the front panel. The<br />
second set of tests actually measures the <strong>DS335</strong>'s specifications. The<br />
results of each test may be recorded on the test sheet at the end of this<br />
section.<br />
The following equipment is necessary to complete the tests. The suggested<br />
equipment or its equivalent may be used.<br />
