If you have difficulty achieving the
±
0.3 dB setting, then make the
following analyzer settings:

Repeat
step 5
7. Divide the marker delta frequency in hertz by the marker delta
amplitude in dB to obtain the slope of the resolution bandwidth
filter. For example, if the marker delta frequency is 1.08 kHz and the
marker delta amplitude is 3.92 dB, the slope would be equal to
75.3 Hz/dB. Record the result below:
Slope ____________ Hz/ dB
