Performance Test 15
The purpose of this test is to verify that the Test Set meets the
specification limits in PTR (Performance Test Record) Table 9-15, “AF
Analyzer DC Level Accuracy Test 15 Record,” on page 265. To measure
DC level accuracy, a DC signal is measured by an external digital multi
meter and compared to the Test Set’s internal DC voltmeter reading.
