求翻译:With the squelch facility switched off, a test signal of +30 dBV, at a carrier frequency equal to the nominal frequency of the receiver and modulated by the normal test modulation shall be applied to the input terminals of the receiver. An audiofrequency load and the psophometric filtering netwo是什么意思? 待解决

与静噪设施关掉30分贝v,一个测试信号,在载波频率等于正常测试调制的接收器和调制的标称频率,应施加到接收器的输入端子。须连接到接收机的输出端的audiofrequency负载和估量噪声滤波网络。应被设置成中定义5.5.1.3产生额定audiofrequency的输出功率输出功率控制接收机audiofrequency。
