IEC 60107-3:1988标准主要适用于使用子载波系统的多声道电视接收机。该标准规定了电性能测量的方法和要求，包括接收机的输入电阻、输入电容、输入电压灵敏度、输入电平范围、输出电平、输出电阻、输出电容、输出电压灵敏度、输出电平范围等方面的测量。

在进行电性能测量时，需要使用特定的测试设备和测量方法。例如，对于输入电阻的测量，需要使用特定的测试信号源和电压表，以确保测量结果的准确性和可重复性。对于输出电平的测量，需要使用特定的测试信号源和示波器，以确保测量结果的准确性和可靠性。

除了电性能测量外，IEC 60107-3:1988标准还规定了多声道电视接收机的其他性能要求，例如音频输出的频率响应、失真度、信噪比等。这些要求旨在确保多声道电视接收机能够提供高质量的音频输出，以满足用户的需求。

需要注意的是，IEC 60107-3:1988标准只适用于使用子载波系统的多声道电视接收机。对于其他类型的电视接收机，需要使用其他标准进行电性能测量和评估。
