Variable Gain Unit


The system provides fixed gain &/ or attenuation control of L-Band or IF based signals, which can be used for balancing during commissioning to overcome differences in cross-site cable losses, as well as providing a useful facility for earth station operators to adjust the gain of UpLink/ DownLink chains remotely.
It is a multi-channel variable gain unit which can accommodate up to 10 MVG00x variable attenuation channels or MFG00x fixed gain channels, each of which are modular, ‘hot-swappable’ and can be inserted/ replaced in the VGU010unit from the rear without the need to remove power or disturb the other channels in any way.
The chassis is mains powered with dual (redundant), modular, hot-swappable power supplies, as standard.
