Since the control sequence can be executed by selecting and designating the operation unit 31, even a person who does not have specialized knowledge can easily control the device under measurement.

  In addition, since the trigger generation command can be created by including it in the control sequence, the processing of the measurement signal generator 21 and the signal analyzer 23 can be linked in association with the control of the device under measurement.

  In addition, since the execution interval between each control command executed in the control sequence can be arbitrarily set, the interval of the control commands given to the device under test can be arbitrarily set within the series of control sequences. It is possible to perform correct control according to the specifications of the device, and it is possible to know the tolerance of the device under test with respect to the interval for giving the command.

  In addition, a control command display field in which the control commands defined for the device under test can be edited, and the name of the desired control sequence and a plurality of control commands executed for the desired control sequence are executed in a tree shape. The control sequence tree display column arranged in order is displayed on the same screen of the display unit, and the control command displayed in the control command display column can be registered in the control sequence tree display column by operation from the operation unit, and its control When a control sequence displayed in the sequence tree display field is selected and operated, the control sequence selected for the device under test is selected on the same screen.
