Abstract
A subscriber line tester for communication lines that convey high speed digital data, wherein a transmission side tester is provided that divides a measuring frequency region into two or more blocks, generates multi-sine waveforms obtained by combining sine waveforms of two or more frequencies in each block, and outputs the multi-sine waveforms to the communication line; and a reception side tester is provided that measures the multi-sine waveforms in the most suitable range for each block, and synthesizes a spectrum from each spectrum obtained for each block, so that high speed communication and long time period measurement are improved.
