在数字广播发射系统中,什么是我们需要考虑的最重要的因素?在广播发射设备的运行过程中,精确而可靠地测试发射机输出功率一直是一项重要工作。另外,天馈线系统的驻波比和回波损耗也是极其重要的因素,因为这两项指标会直接影响到系统的发射能量。这些项目的测试在以前的模拟发射 What is the most important factor we need to consider in a digital broadcast transmission system? Accurate and reliable testing of the transmitter output power has always been an important task in the operation of broadcast transmitting equipment. In addition, the standing-wave ratio and return loss of the antenna feeder system are also extremely important factors because these two indexes will directly affect the system’s transmitted energy. The tests of these projects were launched on previous simulations
