PROBLEM TO BE SOLVED: To improve usability by eliminating complex operation.SOLUTION: An emphasis addition device 1 generating and adding an emphasis waveform for emphasizing a digital test signal inputted to a test object includes an operation display unit 2 for inputting the EYE amplitude on an emphasis waveform image 11 added to the test signal, and the ratio of each tap for the EYE amplitude, a set value calculation unit 5 for calculating the output amplitude on the basis of the EYE amplitude inputted from the operation display unit 2 and the ratio of each tap for the EYE amplitude, and an emphasis waveform addition unit 6 for generating an emphasis waveform based on the output amplitude calculated by the set value calculation unit 5, and adding to the test signal.SELECTED DRAWING: Figure 1 |
