Gainmaker® 1.2 GHz Forward Cable Equalizer
Forward cable equalizers are used during station balancing to compensate the tilt produced by coaxial cable in order to achieve the desired flatness.
Gainmaker® 1.2 GHz Inverse Equalizer
Simulates cable equivalent tilts (creates tilt opposite that of equalizers). Use in place of forward input EQ as needed to maintain proper output tilt in short spaced locations.
Gainmaker® 1.2 GHz Forward Linear Equalizer
Forward Linear Equalizers produce linear tilt. A Linear Equalizer will need to 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 (52-1218 MHz).
Usage: GainMaker System Amplifier, Line Extender, and Node
204 Mhz Reverse Equalizers
Digicomm offers a complete line of 204 MHZ Reverse Equalizers from 1 dB through 20 dB in 1 dB increments. The reverse equalizers are designed to produce a tilted frequency response opposite of what is produced by the coaxial cable.
1.2 GHz Attenuator Pads
Digicomm offers a complete line of 1.2 GHz Attenuator Pads from 0 dB to 20.5 dB in 0.5 dB increments and 21 dB to 25 dB in 1 dB increments, as well as a 75 ohm terminator. Pads are used to attenuate excess signal and to produce flat loss across forward and reverse frequency spectrums. Pads are used during station balancing to adjust amplifier signal level as needed. The dB loss produced is equal to the value printed on the pad.
Tolerance:
+/- 0.3 dB (0 dB - 14.5 dB)
+/- 0.5 dB (15 dB - 25 dB)
1.2 GHz Signal Directors
Digicomm offers a complete line of 1.2 GHz Signal Directors. Signal Directors are used in High Gain Dual and Low Gain Dual system amplifiers only. An amplifier requires one signal director to route and/or split the forward RF signal to the Auxiliary output port(s). The signal director is available as a jumper, splitter, and directional coupler.
GigaXtend GMC Amplifier Accessories
The ATX GigaXtend™ GMC Series amplifier accessories are plug-in devices common to all Cisco or ATX GainMaker System Amplifiers and Line Extenders. They are typically field-installed in accordance with system design.
Mid-Split and High-Split Amplifier Upgrade Kits
85/102 Split Kit for Gainmaker Amplifiers & GS7000 Nodes
With the explosive demand for return path bandwidth, cable operators can increase capacity by upgrading their returns from 5-42 MHz to 5-85 MHz. Digicomm’s family of 85/102 Split Kits are designed to enable the upgrade of GainMaker Line Extender, GainMaker System Amplifiers and the GS7000 Node to 5-85 MHz.
Each Split Kit contains everything needed to upgrade a single amplifier or node.
