8. Chapter 1 Description Functional Description Antenna The antenna types include a roof antenna mechanical window antenna self adhesive window antenna or wall antenna All antennas include a GPS receiver amplifier and intermediate frequency IF downconverter The GPS Receiver extracts a clock signal from the GPS satellite signals The receiver can process the signals from all satellites in view while simultaneously using the Earth location of the receiver and other factors to determine an accurate clock signal An internal amplifier provides signal gain The downconverter converts the L1 band GPS signal to IF for long distance transport on the coaxial antenna cable The antenna cable provides current from the shelf to the antenna and transports GPS satellite IF signals from the antenna to the shelf Antenna Installation and Lightning Protection The TimeSource 3500 standard wall antenna kits do not include lightning protectors When the antenna is installed on the side of the building the antenna is in the zone of protection and is protected from lightning strikes as described in the Standard for the Installation of Lightning Protection Systems NFPA 780 2000 edition The zone of protection shall include the space not intruded by a rolling sphere having a radius of 150 ft 45 72 meters Where the sphere is tangent to earth and resting against a strike termination device all space in the vertical plane between the two points
9. Commands E Notes 1 The time value can only be entered when MODE LOCAL or in the same command as MODE LOCAL otherwise the command is denied A successful command with time changes the display of time to conform to the nearest 30 minutes relative to UTC For example when the UTC time is 01 12 10 setting the local time to 18 50 30 will actually set the clock to 18 42 10 because 18 42 10 is the closest 30 minute jump relative to UTC from 18 50 30 This is done to accommodate 30 minute time zones and still keep the local time accurate to UTC 2 lfa command includes MODE UTC and the GPS signal is not present the command is denied The date time behavior is as follows During warm up The date time displayed starts from 1970 and increments from there If the ED DAT command is used to set the time in local mode the time is changed as specified in the command wm After warm up If the ED DAT command has not been used to set the local mode time then UTC date and time are displayed If the ED DAT command has been used to set the local mode time then it is changed in the manner described as follows The date given in the ED DAT command is retained The local hours minutes and seconds are set to the nearest 30 minute divisible difference from UTC A few examples will help to clarify Example 1 UTC time 01 00 00 Local time 18 01 10 will set the local time to 18 00 00 Example 2 UTC time 01 00 00

28. Holdover Behavior In the TimeSource 3500 alarms are designed with a built in hysteresis This means that an alarm is not announced as soon as some error condition is detected There is a pre integration time during which the error must persist in order for the alarm to be announced On the flip side the error must be clear for a certain time for an alarm condition to be cleared This ensures that intermittent conditions are not flagged unnecessarily During the normal working of the TimeSource 3500 it is a very common occurrence that the GPS satellites may not be visible during certain parts of the day depending on the installation of the antenna This is particularly true with wall and especially window antenna installations The TimeSource 3500 has been designed to work around this situation The TimeSource 3500 enters Bridging mode when all satellite locks are lost There is no TL1 annunciation that the system has entered Bridging mode This is Non Service Affecting and the outputs are not affected The system runs off its internal oscillator and the outputs are kept within the GR 2830 PRC mask by the BesTime engine When Bridging mode persists for more than 30 minutes the system enters Holdover mode and a Holdover event is generated This may or may not affect the outputs depending on the alarm integration parameters that can be set by the user The system allows the user to set various parameters for GPS error Holdover
