Chapter 2 Receiver System Overview
2.3.1 Optional LNA Power Supply
Power for the antenna LNA is normally supplied by the receiver but not, for example, by the OEMV-
2 card. If a different type of antenna is required that is incompatible with this supply, then you could
connect an external power source to the receiver. See also Antenna LNA Power on Page 51.
2.4 Principal Power Supply
A single external power supply capable of delivering the minimum receiver voltage necessary to
operate the receiver. Minimum voltage varies per card, see Table 3, Voltage Input Range for OEMV on
Page 35 and Appendix A, Technical Specifications on Page 129 for details.
WARNING: If the voltage supplied is below the minimum specification, the receiver will
suspend operation. If the voltage supplied is above the maximum specification,
the receiver may be permanently damaged, voiding your warranty.
2.5 Data Communications Equipment
A PC, laptop or other data communications equipment is necessary to communicate with the receiver
and, if desired, to store data generated by the receiver.
