Cisco GainStar Forward Linear Equalizers
Cisco GainStar Forward linear equalizers produce linear tilt. A linear equalizer should be used in the plug-in input
or output equalizer location if a node output tilt does not have the desired station output tilt. The rated upper
frequency (862 MHz or 1000 MHz) and rated 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 nodes and mini
nodes only.
