Abstract: A measurement parameter input control method and a measurement parameter input control device are provided which can intuitively change measurement parameters, which are set for a target device and are necessary for various measuring processes, with high operability.

Abstract: When an operating unit is operated to designate an arbitrary width W and an arbitrary angle ?, a mask region limiting unit limits the effective range of a reference mask set for compliance measurement of the data signal to be evaluated by a reference mask setting unit to the range determined by the designated width and angle and displays the limited effective range on a display unit. When the mask region limiting unit limits the effective range of the reference mask, a quality evaluating unit performs compliance measurement and quality evaluation for the limited effective range in operative association with the limitation of the effective range.

Abstract: A plurality of display windows corresponding to a plurality of applications is formed from a plurality of fixed window frames that is displayed with regularity on one display screen of a display unit. A display control unit performs display control by sequentially displaying displays relating to the plurality of applications in a switching manner in the order in which the plurality of applications is selected in a time series in the fixed window display frames that are displayed with regularity on one display screen of the display unit when the plurality of applications is selected in the time series.

Abstract: In order to easily and efficiently carry out various characteristic evaluations of optical fibers which have been laid down, a table file which is for carrying out association of optical fibers serving as measuring objects with measured data when the optical fibers have been measured, based on optical fiber management information provided in advance of undertaking a cable laying/maintenance construction, such as various types of information on the optical fibers serving as measuring objects, and information on a construction site, and the like, is created at an external terminal. An OTDR measures the optical fibers serving as measuring objects based on the table file created at the external terminal, and stores measured result data in which the measured optical fibers and measured data of the optical fibers have been associated with one another, and edited result data expressing edited contents when the table file and the measured result data have been edited.
