5. Resolution Bandwidth Selectivity Test
2 - 1 6 P e r f o r m a n c e T e s t s
6. Read the 60 dB bandwidth for the 3 MHz resolution bandwidth
setting from the MARKER A frequency readout (see Figure 2-7)
and record the value in Table 2-9.
7. Vary spectrum analyzer settings according to Table 2-9. Measure
the 60 dB bandwidth for each resolution bandwidth setting by the
procedure of steps 4 through 6 and record the value in 'fable 2-9.
8. Record the 3 dB bandwidths from Table 2-8 in Table 2-9.
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
10. The 60 dB bandwidth for the 10 Hz resolution bandwidth setting
should be less than 100 Hz.
