Error rate measuring device and error rate measuring method

摘要

PROBLEM TO BE SOLVED: To provide an error rate measuring device capable of flexible state transition. An error rate measuring device (1) inputs a specific pattern defined by a high-speed serial bus standard to a device under test (W) and tests the known pattern in a state where the device under test (W) is transited to a pattern signal folding state. A signal is input, and the bit error rate of the input data received from the device under test W is measured in accordance with the input of the test signal. The display unit 5 that displays the pattern setting screen 5a for setting a specific pattern, and the pattern The control unit 6 controls the display unit 5 so that the specific pattern on the setting screen 5a is switched to the pattern edit screen 5b that can be edited in block units and displayed.
