VGU010 – 10-Channel, Modular, Variable Gain Unit

The VGU010 system provides Gain 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.

The VGU010 system provides Gain 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.
The VGU010 is a multi-channel variable Gain unit which can accommodate up to 10 MVGL001 attenuation channels, each of which are modular, ‘hot-swappable’ and can be inserted/ replaced in the VGU010 unit from the rear without the need to remove power or disturb the other channels in any way.
The MVG001 adjustable Attenuator modules are available for use at either IF (70MHz 18MHz/ 140MHz 36MHz) or L-Band (950-2150MHz) and can be positioned in either the UpLink or DownLink chain. Each module houses a single adjustable IF or L-Band Attenuator channel and can be fitted with fail-safe switching option.
The VGU010 chassis is mains powered with dual (redundant), modular, hot-swappable power supplies, as standard.
