Specifications
Tables 1 through 14 provide product specifications for the Cisco GainStar accessories.
Cisco GainStar Forward Cable Equalizers
Cisco GainStar Forward cable equalizers produce a tilted frequency response opposite of that produced by coaxial
cables. To achieve the desired output tilt, they are normally used during station balancing to counteract the tilt
produced by coaxial cables. An equalizer’s “dB value” indicates the amount of tilt (in dB) that the equalizer
produced by coaxial cables. An equalizer’s “dB value” indicates the amount of tilt (in dB) that the equalizer
produces from 54 MHz to the rated upper frequency. The rated upper frequency (862 MHz or 1 GHz) and rated
equalizer (EQ) range are marked on the side of each equalizer. A PAD with the same value (in dB) is selected
when a certain EQ value is needed. These accessories are used in the amplifier and line extenders only.
