  • Error rate measuring apparatus and error rate measuring method
    Patent number: 11977464
    Abstract: An error rate measuring apparatus detects a bit error of input data returned from a device under test with transmission of a test signal at an error detector, and includes a log recording unit that records log data of state transition of each lane by handshakes of a plurality of lanes in a predetermined communication standard with respect to the device under test in making the device under test transit to a state of LOOPBACK, and a display unit that displays the recorded log data of the state transition of each lane in a time-series order.

  • Error detection device and error detection method
    Patent number: 11934282
    Abstract: The state transition condition can be adjusted flexibly and easily while taking advantage of the handshake-type technique. A state transition setting screen 11 of an entire state transition flow including a name 12 of each state based on a communication standard and a state transition condition 13 to be executed between states is displayed on a display screen 6a, and input setting for the state transition condition is possible on the state transition setting screen 11.

  • ERROR DETECTION DEVICE AND ERROR DETECTION METHOD
    Publication number: 20230116669
    Abstract: It is possible to intuitively identify the reason for the handshake failure. An entire state transition flow including each state based on the communication standard and a state transition condition to be executed between states is displayed as a state transition setting screen 11, and an immediately preceding state in which the state transition fails and the failed state transition condition are highlighted on the state transition setting screen 11, when the handshake with the device under test ends.
