5. Using a CATV Signal Level Meter, verify the RF output levels at the –20 dB test point on the
AR, as shown in Table 4.3. This assumes that the optical levels into the receivers are flat.
6. If the levels at the –20 dB test point are not correct, adjust the pad and equalizer values as
necessary and repeat the previous step until they are within tolerance.
