  • Page 129: Ntp Option

    NTP Option The SRG-4500 always contains the hardware and associated circuitry necessary to allow operation of the NTP Option. This chapter provides information on the NTP option for your SRG-4500.  An Option Key is required to enable the NTP Option. No additional externally connected hardware is required as part of the installation.

  • Page 130: Configuring The Srg-4500 Overview

    SRG-4500 operates in unicast mode, making it suitable to be polled by a number of Stratum 2 servers. Optionally the SRG-4500 can be set to client mode, allowing the unit to get its clock time from a single upstream server.

  • Page 131: Simplified Ntp Flowcharts

    • Once the time-code has been set by the NTP Client, the SRG-4500 should not need to re-check the NTP time unless a crash lock has been forced by the phase locking arrangement.

  • Page 132: Required Time Corrections

    Required Time Corrections From an NTP Server, the SRG-4500 Master Clock can derive UTC and also add the appropriate time offset and provide corrected local time. Table 15.1 contains a list of the various corrections which need to be made by the SRG-4500.

  • Page 133: Gps Option

    Keep the following in mind before installing your antenna and connecting it to your SRG-4500: • Ensure the Option Key for the GPS feature is enabled on the SRG-4500. Refer to the section “Option Enable Menu” on page 88 for details.

  • Page 134: Recommended Cables

    With the GPS Option enabled, the SRG-4500 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.

  • Page 135: Connecting The Srg-4500 To The Gps Antenna

    Figure 16.4 Securing the Antenna Cap Connecting the SRG-4500 to the GPS Antenna There are two methods of connecting the SRG-4500 with a GPS antenna: with an external line amplifier and without an external line amplifier. This section summarizes both methods.

  • Page 136: Connection With A Line Amplifier

    Connection with a Line Amplifier The SRG-4500 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.

    • However, in marginal reception, the timecode update should be suppressed until it has been valid for a number of seconds. • Once the time-code has been set by the GPS receiver, the SRG-4500 should not need to recheck the GPS time unless a crash lock has been forced by the phase locking arrangement.

  • Page 140: Signal Requirements

    Thermal noise is -174dBm/Hz at room temperature. From this we can compute a system noise figure of 4dB for the SRG-4500. 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.

Keep the following in mind: • The Global Navigation Satellite System (GNSS) only transmits a complete UTC-GNSS time message once every 12.5 minutes.

    Check if the +5V is now present on the frame GPS connector. e. If so, problem is likely with the antenna system. 4. If 5V is present at the SRG-4500 rear panel, verify that +5V is also present at the GPS antenna: a. Remove the cable from the GPS antenna, b.

  • Page 144: Antenna Setup

    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-4500 can reject CW in-band jamming signals, but would still be affected by non-CW signals. It is recommended to move the antenna away from any source of interference or shield the RF interference to prevent it from getting to the antenna.

    The PTP engine serves TAI time. If the Grandmaster is GPS or VITC locked, you cannot change the time PTP is serving. If the SRG-4500 is set to free run mode, it will serve TAI time based on the SRG-4500 UTC time. The SRG-4500 User Guide (v7.0)

    To reduce the number of configurations, the AES created AES56-R16:2016, a set of recommended values that map between the AES and SMPTE profiles. To simplify setup of the SRG-4500, both SMPTE and AES67-R16 profiles can be selected to automatically set the parameters to these default values.
