    System Requirements The SRG-4400 requires an Option Key to enable the GPS sub-system. Additional optional GPS components are available when the GPS Option is ordered as part of your system. The system works best with a GPS signal level between -125dBm and -117dBm at the SMB plug at the rear of the unit.

    With the GPS Option enabled, the SRG-4400 provides a 5 volt DC voltage that is impressed upon the RF signal line. The current is internally limited to 50mA. The Ross supplied antenna and line amplifier (optional equipment) require less than 30mA combined.

    Connecting the SRG-4400 to the GPS Antenna There are two methods of connecting the SRG-4400 with a GPS antenna: with an external line amplifier and without an external line amplifier. This section summarizes both methods. Note that the information presented in this section may differ from the requirements of your facility.

  • Page 181: Connection With A Line Amplifier

    Connection with a Line Amplifier The SRG-4400 can be used with an external Line Amplifier when a long cable run is required. Because of the internal LNA, the overall gain (including signal losses past the external Line Amplifier) should not exceed 35dB. Levels higher than that can affect the jamming detection capability of the SRG-4400.

    Frequency lock can be established in a few seconds as the oven free-running frequency is within a few ppm of the GPS frequency at all times. The first time the SRG-4400 is powered with a GPS receiver, the SRG-4400 waits for 3 or more satellites to be “fixed”, then the SRG-4400 acquires frequency lock.

    -147dBm at its input. This means the SRG-4400 can find the necessary satellites, download the necessary ephemeris data and compute the location within a 5 minute period. The SRG-4400 will display a reported C/No of 40dB-Hz for a signal level of - 130dBm into the RF input.

    Thermal noise is -174dBm/Hz at room temperature. From this we can compute a system noise figure of 4dB for the SRG-4400. This noise figure consists of the loss of the preselect SAW filter, the noise figure of the LNA as well as implementation losses within the digital signal processing unit.
  • Page 185 As mentioned earlier, the GPS and GLONASS signals are at -130dBm and lower. If signals higher than this are presented to the receiver it can be overwhelmed. The SRG-4400 can reject CW in-band jamming signals, but would still be affected by non-CW signals.
