Page 8: General System Information
3. General System Information The MVRD (Messenger VETA Receiver Decoder) receives and demodulates DVB-T 2k carriers’ signals with bandwidths of 6, 7 or 8 MHz; additionally, optional 1.25 or 2.5 MHz RF bandwidths with 400 carriers allow both increased reception range and larger quantity of simultaneous A/V links to operate in the same frequency band. -

4. MVRD Local Control Introduction As with all GMS Cobham surveillance products, the MVRD uses “Set-Up Groups”/ “Profiles” (Up to 16) to allow the receiver to be completely pre-configured by Administrators prior to deployment. These set- up groups define all of the operating parameters (e.g. frequency, bandwidth, FEC, Decryption On/Off) available to the users. -
