Block Down Converter Module (BDC-4000) Operating Parameters

The BDC-4000 translates a band-specific input frequency block (C-, X-, or Ku- or Ka-Band)
from the LNA down to L-Band (950 to 2000 MHz).

Monitoring Operations via the LED Indicators

The MBT-4000 Multi-Band Transceiver System features two Light-Emitting Diode (LED)
indicators – one for each operational unit (module). Each LED provides the user with visual cues
to the operational, online, and offline status of the sytem.

Figure 4-1 illustrates the location of the LED Indicators. Located on the top of the MBT-4000’s
Base Module under a pivoting protective plate, the LEDs may be viewed by loosening the
thumbscrew that keeps the plate in place; the user can then swing the plate away to reveal the
LED display window.

Appendix B. FAULTS/EVENTS provides complete details for interpreting the LED Indicators.
