广电部设备制造厂研制的TF 520型10KW调频广播发射机,由于具有一些出色的特点,问世后随即跻身于世界先进行列。现简述其中几个特点: 一、技术指标很高 当配用美国BE公司的激励器时,整机的技术指标和当前世界著名公司产品的指标相比,毫不逊色。在相同的测试条件下,信噪比实际优于80dB;频响远优于±0.5dB;失真度实际达0.1％;左右信号分离度大于48dB;总的说,可以通过和
The TF 520 10KW FM radio transmitter developed by the equipment department of the Ministry of Radio, Film and Television, ranks among the advanced countries in the world immediately after its publication due to its outstanding features. Here are some of the features outlined: First, high technical indicators When equipped with the United States BE company’s incentives, the whole technical indicators and the current world-renowned company’s products compared to indicators, no less. In the same test conditions, the signal to noise ratio is actually better than 80dB; frequency response is far better than ± 0.5dB; distortion actually up to 0.1%; left and right signal separation greater than 48dB; in general,
