11 In this example, the attenuation over this frequency range is

- 17.98 dB/octave (one octave above the cutoff frequency).

12 Use the front- panel knob to place the marker at the highest

peak in the stop band to determine the minimum stop band

attenuation. In this example, the peak occurs with Delta of

563 MHz. The attenuation is - 60.93 dB. See Figure 21
