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.
15.Set the 8566A/B controls as follows:
Center frequency ................................................ 10.710 MHz
Resolution bandwidth ................................................ 10 kHz
Video bandwidth ........................................................... 1 kHz
Sweep time .................................................................. 200 ms

17.Figure 9-23, "Output Waveform, 1 kHz Resolution Bandwidth"
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, U803, U804, or
U106.
