PURPOSE:To improve the performance of the characteristic test corresponding to a transmission line and a communication equipment receiving and sending a burst signal. CONSTITUTION:This detector is provided with a start signal generating section 2, a memory 4 storing a test data, a data generating circuit 3 reading the data from the memory 4 and outputting the data and a buffer memory 5 storing the data from the circuit 3. A frame composition circuit 6 receiving an input data TD2 from a buffer memory 5 and a TD/EBL signal from the circuit 3 outputs a frame subject to capsule processing. A driver circuit 7 converts the frame and outputs the converted frame to a sample 14, and a frame decomposition circuit 9 receives the signal sent back from the sample 14 via a receiver circuit 8 and extracts the data from the frame and outputs the data, a data collation circuit 11 collates the data entered via a buffer memory 10 and the data from the buffer memory 5 to detect an error and it is informed by a display device 13 or the like. |
