Patent number: 8237921Abstract: At the time of real-time measurement, when a measurement position is specified by a marker, a marker level acquiring section acquires a waveform level from waveform data stored in a waveform memory. A level comparing section determines whether the waveform level acquired by the marker level acquiring section falls within an effective measurement level range preset correspondingly with attenuator (ATT) values. When the level comparing section determines that the waveform level does not fall within the effective measurement level range, an ATT value change section changes the ATT values into new ATT values at which a waveform level falls within the corresponding effective measurement level range. A control section allows a measured optical fiber to be measured based on the new ATT value, so as to enable waveform measurement with a good S/N ratio of not less than a predetermined value based on a measurement waveform displayed on a screen of a display section.Type: GrantFiled: June 20, 2007Date of Patent: August 7, 2012Assignee: Anritsu CorporationInventor: Shigeo Hori

Publication number: 20100271622Abstract: When a measurement position is specified by a marker during real time measurement, a marker level acquisition unit acquires a waveform level from waveform data stored in a waveform memory. A level comparison unit judges whether the waveform level acquired by the maker level acquisition unit is within an effective measurement level range set in accordance with a currently selected attenuator (ATT) value. If the level comparison unit judges that the waveform level is out of the effective measurement level range, an ATT value modification unit modifies the ATT value to a new ATT value so that the waveform level is contained in the corresponding effective measurement level range. According to the new ATT value, a control performs measurement of an optical fiber to be measured so that a waveform can be observed with a preferable SN ratio above a predetermined value according to the measured waveform displayed on a screen of a display unit.Type: ApplicationFiled: June 20, 2007Publication date: October 28, 2010Applicant: Anritsu CorporationInventor: Shigeo Hori
