6 dB resolution bandwidth measurements are used in Performance
Test 5, Impulse and Resolution Bandwidth Selectivity Test.
Figure 4-3. 6 dB Resolution Bandwidth Measurement
46. Select the spectrum analyzer [BW] and
settings according to Table 4-3. Press SWEEP (?iKiF] and
measure the 6 dB bandwidth for each resolution bandwidth
setting using the procedure of steps 43 through 45 and record the
value in Table 4-3. The measured bandwidths for 300 Hz, 100
Hz, 30 Hz, and 10 Hz should fall between the limits shown in the
table.
