Resumen del manual
A wide range of settings, electronic operation and excellent technical data – at an unbeatable price/performance ratio. VGP 9033-1G/9041 – VGF 9030/9040 • Modern, monitorable compact amplifiers for interactive HFC networks • Innovative operational concept: Using electronic tuning elements, set using HTE 10 hand-held unit (fewer plug-in cards and attenuation pads required, repeatable device settings) • Integrated frequency-agile 2-pilot control in VGP 9033-1G/9041enables quick commissioning: Automatic levelling in the forward path, thus no need for time-consuming manual levelling Automatic presetting of the return path is possible • Remote configuration of all setting parameters via monitoring system (can be activated/deactivated) • High gain (up to 40 dB), variable in interstage position • Latest GaAs-MMIC technology • Very high output levels at lowest intermodulation products, even for interstage operation • Loop-through input (only for VGP 9033-1G/9041) and output splitter can be configured • De-emphasis (inverse-equalisation) insert position • Remote feeding: 7 A per input/output, local feeding: 10 A • Insert position for monitoring transponder (HMS/DOCSIS) • Test sockets on input/output and in return path amplifier • Integrated return path amplifier, settable gain • Ingress Control Switch • Aluminium die-cast housing with PG 11 connections "Plug-and-Play" redefined Electronic setting of all important parameters, automatic levelling (only for VGP 9033-1G/9041) as well as remote configuration via HMS or DOCSIS monitoring ensure the shortest start-up and maintenance times. The copy function enables one to copy all settings and transfer them to another device at the press of a button. The absence of plug-in cards for gain and slope not only accelerates start-up, but also simplifies logistics and saves warehousing costs. Another advantage during modifications: new values are taken over without any interruptions. Multimedia services remain undisturbed. Start-up without a measuring instrument – it doesn't get any easier than this Due to automatic levelling, the compact amplifiers VGP 9033/9041 can be put into operation with just a few steps: - Simply enter the desired output level for the lower and upper pilot frequency and start levelling - After a few seconds, the device automatically sets the desired values, whereby optimal technical data are continuously reached. Manual vernier adjustment is still possible at any time. - Subsequently, automatic presetting can also be effected in the return path. - For the next devices, levelling runs even more quickly. The copy function enables desired settings to be automatically incorporated.
