    Multi-Band Transceiver System Revision 0 Introduction MN/MBT4000B.IOM 1.3 S YSTEM VERVIEW The transceiver is constructed in a modular configuration. Common to the configuration for any frequency band of operation is a base module, which provides the M&C, Power Supply, and Reference function. A Band-specific BUC module is mounted to the base module with clip-type fasteners.

    Chapter 3. System Operation 3.1 D ESCRIPTION The MBT 4000B supports LNBs for receive down conversion. It outputs +17VDC nominal and 10 MHz on the “L-Band input” connector. The LNB amplifies the input RF signal and down converts it to L-Band in the range of 950 to 1750 MHz (there may be instances that the L-Band range = 950 to 1450 MHz ).

  • Page 29: Chapter 4. Redundant Configuration

    The MBT-4000B is designed to operate in both stand-alone and redundant configurations. Every MBT-4000B base contains the circuitry and logic necessary to perform all the functions of a backup controller in either a single base and dual base configuration. The Bias Tee side of the MBT 4000B provides the 10 MHz reference and DC voltage for the LNB.

  • Page 30: Dual-Base (Chain) Redundancy Operation

    In dual base (chain) redundancy operation, the redundancy is ‘slot’ based. The corresponding pairs reside in the same ‘slot’ of the opposite MBT-4000B base, the pair of BUCs connected to J3 UNIT 1 COMM (slot 1) on each base form a redundant pair. The LNBs connected to “L BAND IN”...

  • Page 31: External Fault Monitoring

    0 for disabled, or 1 for enabled LNB Power Supply Current Monitoring The bias tee in the MBT-4000B base is used to supply power and the 10 MHz reference to the LNB. This power supply features current monitoring with programmable failure limits. Over-current and under-current failures can participate in overall fault indication and redundant switchover criteria.

  • Page 32: Gain Equalization Of Redundant Units

    If a current is detected outside this window, a LNB current fault will be posted, but the supply will not be disabled. Gain Equalization of Redundant Units Uplink Gain equalization in an MBT-4000B system is accomplished by issuing individual attenuation settings to the specific BUCs. LED Status Indicators...

  • Page 37: Appendix A. Remote Control

    Appendix A. Remote Control This section describes the protocol and message command set for remote monitor and control of the MBT 4000B. The electrical interface is either an RS-485 multi-drop bus (for the control of many devices) or an RS-232 connection (for the control of a single device), and data is transmitted in asynchronous serial form, using ASCII characters.
