무선 송신기의 측정방법-제4부:무선 전화 및 라디오 방송용 송신기의 진폭/주파수 특성 및 비선형 왜곡 无线电发射机测量方法第4部分:无线电话和声音广播发射机的幅度/频率特性和非线性失真
发布日期: 2008-08-08
在该标准中,必须与IEC60244-1兼容,如果可能的话,建议与其他部分一起使用,该标准讲述了在无线发射机的输出中,为测量信号质量而使用的方法和条件。这种测量方法可适用于下列情况:-用于无线电话(radiotelephony)或声音广播(sound broadcasting),用于利用全载波(full carrier)的调幅发射机(amplitude-modulated发射机)-通道小于4个的单通道或多通道无线电话。利用低衰减载波(reduced carrier)或压制载波(impressive carrier)的调幅发射机-单声道(monophonic)音频广播用调频发射机1)在某些情况下,也可以用于多频道音频电报(voice-frequency telegraphy),也可以用于利用低衰减载波或压制载波的调幅发射机。
IEC 60244-1과 병용되어야 하고, 가능하다면 다른 부분과도 함께 활용할 것이 권장되는 이 표준에 서는 무선 송신기의 출력에서 신호의 품질을 측정하기 위해 사용되는 방법 및 조건에 대해 다룬다. 이러한 측정방법은 다음에 적용될 수 있다. - 무선전화(radiotelephony)나 음향방송(sound broadcasting)용으로서, 전반송파(full carrier)를 이용 한 진폭변조 송신기(amplitude-modulated transmitter) - 채널이 4개 이하인 단일 채널 혹은 다중 채널 무선전화용으로서, 저감 반송파(reduced carrier)나 억압 반송파(suppressed carrier)를 이용한 진폭변조 송신기 - 모노포닉(monophonic) 음향방송용 주파수변조 송신기1) 어떤 경우에는, 다중채널 음성주파 전신(voice-frequency telegraphy)용으로, 저감 반송파나 억압 반송 파를 이용한 진폭변조 송신기에도 적용될 수 있다.
