A measuring apparatusincludes: a transmission and reception unitwhich wirelessly communicates with devicestounder test (DUTs); a measurement unitwhich receives data from the DUTs through the transmission and reception unit, measures the DUTs based on the received data and outputs measurement results; a display unitwhich displays predetermined information regarding the measurement; a disconnection related information acquisition unitwhich, on the condition that a connection state of the wireless communication has been changed to a disconnected state, acquires disconnection related information including information indicating a reason for changing to the disconnected state and information on a state immediately before the disconnected state; and a display control unitwhich performs control to display the disconnection related information on the display unit

Measuring apparatus and measuring method

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. The measurement parameter input control device includes: a parameter processing section that acquires measurement parameter information including measurement parameters from a target device and that rewrites changed parameters which are measurement parameters after the changing to the target device; a parameter identifying section that identifies the types of the parameters in the acquired measurement parameter information and outputs soft key constructing information for constructing a parameter setting soft key based on the identified measurement parameter information, a display control section that includes a soft key controller displaying and controlling the parameter setting soft key based on the measurement parameter information on a display screen of a display unit on the basis of the soft key constructing information from the parameter identifying section; and an input unit that operates the parameter setting soft key displayed on the display unit.

Measurement parameter input control device and measurement parameter input control method

When an operating unit is operated to designate an arbitrary width W and an arbitrary angle &#x3b8;, 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.

Data signal quality evaluation apparatus

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. The external terminal generates a report based on the measured result data and the edited result data stored in the OTDR.
