Cisco GainMaker Amplifier and GS7000 Node Accessories Data Sheet
Available Languages
The Cisco GainMaker amplifier accessories are plug-in devices common to all GainMaker System Amplifiers and Line Extenders. They are typically field-installed in accordance with system design. Also included in this document are the specifications for the linear equalizers used in GS7000 and GainMaker Nodes. This document includes the accessories used in products designed for 750, 870, 1002, and 1218 MHz systems.
Forward Cable Equalizers
Forward cable equalizers produce a tilted frequency response opposite of that produced by coaxial cable. They are normally used during station balancing to counteract the tilt produced by coaxial cable, in order to achieve the desired output tilt. An equalizer’s “dB value” indicates the equivalent length of cable (in dB, at rated high frequency) that the equalizer is designed to offset. The dB value and rated high frequency (750, 870, 1002, or 1218 MHz) are printed on the top of each equalizer. The amount of tilt (in dB) that the equalizer produces from low to high frequency is printed on the side of each equalizer.

Forward Linear Equalizers
Forward linear equalizers produce linear tilt. A linear equalizer should be used in the plug-in input or interstage equalizer location if a node output tilt does not have the desired station output tilt. The EQ value is the amount of tilt from lowest to highest frequency (52 – 1002 or 1218 MHz).

Inverse Equalizers
Forward inverse equalizers produce cable equivalent tilt. An inverse equalizer is normally used in place of a forward input equalizer during station balancing when an amplifier is short spaced to achieve the desired output tilt. An inverse equalizer’s “dB value” indicates the amount of tilt (in dB) that would produce similar tilt (loss differential from low to high frequency). As with other equalizers, the 750, 870, 1002, and 1218 MHz inverse equalizer values are printed on the top of each inverse equalizer.

Reverse Equalizers
Reverse equalizers produce a tilted frequency response opposite of that produced by coaxial cables. They are normally used during station balancing to counteract the tilt produced by coaxial cables, in order to achieve desired tilt. An equalizer’s “dB value” indicates the amount of tilt (in dB at rated high frequency) the equalizer is designed to offset. The dB value and rated high frequency (40, 42, 55, 65 or 204MHz) are printed on the top of each equalizer. The amount of tilt (in dB) that the equalizer produces from low to high frequency is printed on the side of each equalizer.
Table 10. Reverse Equalizers - 42 MHz EQs are Used in GainMaker Amplifiers with Either a 40/52 or 42/54 MHz Reverse/Forward Bandsplit. Both the 42 MHz and the 40 MHz EQ Values Are Printed on the Top of Each 42 MHz Reverse Equalizer

Signal Directors
Signal directors are used in the High Gain Dual and Low Gain Dual system amplifiers only. One signal director is required per amplifier to route and/or split forward RF signal to the Auxiliary output port(s). The signal director is available in splitter, DC-8, or DC-12 configurations for splitting the Auxiliary path signal to feed both Auxiliary ports, or as a jumper for routing all signals to a selected port.

Note: The GainMaker plug-in signal director produces loss in the forward signal path only. The signal director is physically located inboard of the forward/reverse diplex filters in the forward path of the amplifier. Therefore, there are no reverse path losses associated. Auxiliary port reverse input pad values must be selected accordingly during system design when using the splitter, DC-8, or DC-12 signal director in a station.
System Trim
A plug-in system trim may be used to counter the frequency response effects of some passive devices in the coaxial plant. A mid frequency, single dip trim (Model MSD-1NGF) is available for all 870 MHz GainMaker amplifiers. The System Trim part number is 714446.

Pads (attenuators)
Plug-in pads produce flat (even) loss across the forward and reverse frequency spectrums. Pads are used during station balancing to adjust signal levels as needed. The (dB) loss produced is equal to the pad value printed on the top of the pad. The Pad with “75 Ω” printed on the top will work as a 75 Ohm terminator.
