4. Resolution Bandwidth Selectivity Test
7. Vary spectrum analyzer settings according to
Table
2-6. 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
‘lhble
2-6.
8. Record the 3
dB
bandwidths from Table 2-5 in
Table
2-6.
9. Calculate the bandwidth selectivity for each setting by dividing
the 60
dB
bandwidth by the 3
dB
bandwidth. The bandwidth
ratios should be less than the maximum values shown in
Table 2-6.
10. The 60
dB
bandwidth for the 10 Hz resolution bandwidth setting
should be less than 100 Hz.
