dB
Resolution Bandwidth Selectivity Test
7. Vary spectrum analyzer settings according to
Table
4-4. Press
SWEEP
(SINGLE)
and measure the 60
dB
bandwidth for each
resolution bandwidth setting by the procedure of steps 4 through
6. Record the value in Table 4-4.
8. Record the 6
dB
bandwidths from Table 4-l in
Table
4-4.
9. Calculate the bandwidth selectivity for each setting by dividing
the 60
dB
bandwidth by the 6
dB
bandwidth. The bandwidth
ratios should be less than the maximum values shown in
‘fable
4-4.
10. The 60
dB
bandwidth for the 10 Hz resolution bandwidth setting
should be less than 100 Hz.
