13. Figure 9-17 illustrates normal operation. Severe failures (slope error greater than 30
percent) and subtle 3 kHz resolution bandwidth errors (less than 30 percent) indicate a
problem with A4U802, A4U803, A4U804, or A4U106.
14. Severe failure of the bandwidth accompanied by subtle errors in the output signal indicate
an A5 failure.
