According to one embodiment, a mobile terminal testing device which tests a mobile terminal including a plurality of transmitting antennas by transmitting/receiving radio signals between the mobile terminal testing device and the mobile terminal, includes a radio signal processing module configured to transmit and receive radio signals to and from the mobile terminal and a controller configured to cause the mobile terminal to switch one from another among the plurality of transmitting antennas by a predetermined radio signal transmitted to the mobile terminal via the radio signal processing module.

Mobile terminal testing device and transmitting antenna testing method

Provided are a mobile terminal testing device for and a mobile terminal testing method of enabling a user to easily recognize a change in the testing result data in each domain in a case where testing result data indicating a result of testing a mobile terminal is displayed with two domains. A three-dimensional display screenon which the testing result data indicating a result of testing the mobile terminal is displayed in a three-dimensional graph that uses the first domain and the second domain, a first display screenon which the testing result data is displayed in a graph that uses the first domain, and a second display screenon which the testing result data is displayed in a graph that uses the second domain are displayed on a display device.

Mobile terminal testing device and mobile terminal testing method

A plurality of touch operation areas which are allocated to a plurality of measurement items for a mobile terminal are set in a touch-panel-type operating unit. A list of sections of the touch operation areas and a list of measurement item names for each section are displayed on a screen of a display unit. A switching button for switching the measurement item which has been invalidated among the measurement items to a valid state is displayed to inform an operator that the measurement item has been invalidated. The measurement results of the measurement item which has been validated are displayed in the sections to inform the operator that the measurement item has been validated.

Mobile terminal test device

To provide an image display device and an image display method capable of causing an image displayed on a display device to be visually recognized without degrading the operability of the user. A scroll amount of an image displayed in an image display area is specified according to an operation of scrolling the image displayed in the image display area, the scroll amount is regulated so that the image displayed in the image display area is not out of the image display area if the image displayed in the image display area is scrolled to be out of the image display area when the image displayed in the image display area is scrolled according to the specified scroll amount, and a display mode of at least a portion of a peripheral area of the image display area is changed.

Image display device, test device using image display device, and image display method

To provide a mobile terminal test apparatus and a mobile terminal test method capable of setting the setting items more easily and more accurately than in the related art and testing mobile terminals. A mobile terminal test apparatusincludes a registered item display screen control unitthat performs a display control operation of displaying a registered item display screen including registered items, a history display screen control unitthat performs a display control operation of displaying a history display screen for displaying the history of the setting items set in the past and test parameter values, and a setting item display processing unitthat performs at least one of a process related to the display order of the setting items and a process related to the deletion of the setting items.

Mobile terminal test apparatus and mobile terminal test method

A mobile terminal testing device includes a reproduction unit that reproduces a BB signal to output at least one reproduced BB signal, an adder that adds a BB signal that are frequency-shifted and a reproduced BB signal to output an added BB signal, an up-converter that generates a multicarrier test signal by making a frequency conversion of the added BB signal of an I phase and Q phase and outputs the multicarrier test signal to UE, and an analyzer that analyzes a response signal output by the UE in response to the multicarrier test signal and the analyzer includes a throughput calculation unit that calculates throughput for the multicarrier test signal and an RSRP acquisition unit that acquires RSRP.

Device to test mobile terminal and testing method thereof

A test apparatus for a mobile communication terminal is provided with a pseudo base station and display and control units. The control unit includes a analysis unit and a tag addition unit. The analysis unit acquires and analyzes the messages from the base station to take out information from the messages. The tag addition unit detects a group of series messages which have a mutual association and are consecutive in time sequence among the messages analyzed and to add a tag for identifying each group of messages to a detected group of messages. The control unit displays the tag together with the series of messages so as to identify the respective groups of messages.

Test apparatus for testing mobile communication terminal and message display method for displaying message associated with the testing

There is provided a technique for smoothly performing position (movement) adjustment of a waveform marker by making switching between rough adjustment and fine adjustment in a series of marker operations possible with a single means and continuously. A display control section displays a measured waveform on the two-dimensional coordinates, which have a first axis and a second axis perpendicular to the first axis, on the display section. A waveform marker is movable by a marker operation corresponding to a direction parallel to the first axis. The display control section has a detecting section, which detects the marker operation corresponding to a direction parallel to the second axis, and changes either setting of the waveform marker or the display range of the measured waveform according to the detection result of the detecting section.

Measuring apparatus and measuring method

[Task] To provide a mobile communication terminal test apparatus capable of displaying an EVM or a transmission power measurement result in a frequency division multiple access communication scheme by distinguishing between the allocation band and the non-allocation band. [Means for Resolution] A test signal including control information representing the communication channel and the allocation band is transmitted to the mobile communication terminal, the test signal output from the mobile communication terminal is received, the output waveform data are analyzed, a measurement value of a predetermined measurement item is obtained on a symbol-by-symbol basis, the obtained symbol-based measurement value is displayed on a graph, and the allocation band on the corresponding graph and the non-allocation band within the communicate channel are displayed to be distinguished therebetween.

Mobile communication terminal test apparatus and test result display method

A signal analyzer for facilitating observation of a relative value, i.e., the quantity of variation in power between slots, at the time of analyzing the power of a signal which is to be measured and subjected to power control in units of slot. An analyzing section detects the power value of every slot of a signal which is to be measured and received at a receiving section, and calculates the relative value of the power value between each slot and a slot separated therefrom by a predetermined number. A display control section displays the relative values thus calculated as a graph at a display section by arranging them continuously in time series.
