CL1TC-4 400W DVB-H Transmitter WEB Interface 6.4.9 HPA Control The HPA Control page contains a drop down menu that allows the user to set the transmitter to one of the following modes: • Standby • Broadcast • Manual Broadcast mode represents normal operation. Standby mode disables the transmitter output. In Manual mode the HPA behaves as a simple amplifier and the modulator control of the HPA output is limited to setting the input drive level to the HPA.
CL1TC-4 400W DVB-H Transmitter WEB Interface 6.4.10 GPS The most important parameter for the GPS menu is the Max GPS Holdover Time parameter. Following a loss of signal lock to the GPS satellite network, the Max GPS Holdover time is the maximum length of time the system will continue to operate in a free-running mode before an alarm is issued leading to a possible transmitter shutdown condition. It is imperative for a SFN network for all transmitters to be synchronized to GPS at all times.
