Description

technical field [0001] The invention relates to a testing technology for electric energy meter carrier communication equipment. Background technique [0002] Carrier communication (Carrier communication) is a telephone multiplex communication system based on frequency division multiplexing technology, which belongs to the standard of classic analog communication; in engineering, the electrical signal spectrum of a telephone line is limited to the range of 300-3400 Hz; considering the protection The frequency interval occupied by one telephone line is 4 kHz; therefore, according to the different frequency bandwidths of practical channels, different numbers of telephone signals are multiplexed within the frequency bandwidth of one channel; at present, the carrier wave of the energy meter The communication test requires a specially programmed "data acquisition terminal" to be used in conjunction with a "carrier copy controller", and this cooperative use has the following disadv...
