Wavecom System 4000 Rackmount Shelf w/ 6 X MA4040D
Up for sale is a Wavecom System 4000 Rackmount Shelf with the following:
* Wavecom MA4011B Rackmount Shelf Power Supply
* Six MA4040D-Frequency Agile 64/256 QAM Upconverter
The MA4040D is a fully agile commercial quality IF upconverter for data over cable and Digital Video-on-Demand applications. Advanced design allows a single MA4040D card to cover a frequency band from 53 to 858 MHz and still maintain a phase noise specification which exceeds the DOCSIS requirements for 64/256 QAM. Remarkably low out of band noise performance and low spurious are achieved through high level mixing, a microwave frequency IF and multiple levels of filtering.
* High level output; +61 dBmV 53 to 858 MHz
* Front panel selectable output frquency in 12.5 kHz step size
* Digital slope compensation to achieve < 0.3 dB slope over any channel
* A range of custom IF input frequencies are available
* Auto IF AGC automatically corrects for input level changes (non-bursty)
* Out of band noise performance <-12 dBmV / -30 dBmV / 6 MHz
* Excellent in-band noise performance
* User defined soft alarms for IF and RF levels can be enabled via remote control
* RF output mutes when changing output configuration
* High reliability, state-of-the-art design using microstrip MMIC and surface mount technology
* Conservative component derating and 100% burn in help ensure reliable operation
* All local oscillators are frequency synthesized and locked to a common internal high stability reference
