Patent number: 8554198Abstract: 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.Type: GrantFiled: February 2, 2012Date of Patent: October 8, 2013Assignee: Anritsu CorporationInventors: Kazunori Aoki, Toyohiro Kayanuma, Takayuki Awano

Patent number: 8194723Abstract: The present invention provides a test apparatus for a 64B/66B encoding process capable of precisely performing a test with a high reproducibility on a certain pattern of a 64B/66B encoder or decoder. A frame generator generates frame data in a layer higher than a physical coding sublayer of Ethernet (registered trademark) and inputs the frame data to a 64B/66B encoder such that the 64B/66B encoder performs a 64B/66B encoding process of the physical coding sublayer with respect to the frame data. A sequence pattern generator generates a certain 66B sequence pattern written in advance, and a controller writes a desired sequence pattern in the sequence pattern generator and, at the same time, controls a data selector to select one of data encoded by the 64B/66B encoder and a sequence pattern output from the sequence pattern generator and to provide the selected one to a test subject.Type: GrantFiled: February 23, 2010Date of Patent: June 5, 2012Assignee: Anritsu CorporationInventors: Tomohiro Ito, Takayuki Awano
