摘　　要：有线电视系统中的各项指标测量方法在国家标准和行业标准中都有明确规定,大多数指标需要几种仪器进行正确的连接后才能准确测量,而且每项指标测量所需的仪器还不完全一致,这给测量工作带来较大的麻烦。根据这种情况,一些生产厂家生产出了有线电视分析仪,如美国惠普公司生产的HP8591C频谱分析仪,即利用一两台主要仪器及其附件可测出有线电视系统的绝大多数指标,这里主要介绍其中的7项指标。Every kind of index sign of the cable TV system have rules in national standard and profession standard. The majority of index sign the demand a few instruments proceed the right conjunction the empress, the talent the accurate diagraph, and each the instrument that index sign need when measuring still incompletely, returnfng to the diagraph work bring the bigger trouble. According to circumstance, some enterprises produces cable TV analysis instrument, then make use of 1 2 main instruments in sets and its enclosure, such as the HP8591C frequency chart analysis instrument it can test to find out the great majority index sign of the cable TV system. The paper introduces 7 kinds among of them.
