• Automatic Setting of Measurement Conditions
  Full Auto Mode
  Simply choose the measured wavelength, then press a button.

The AQ7270 automatically sets the optimal measurement conditions, performs measurement, performs event analysis, and saves data. Because you can save to a different file name each time you execute, measurement and accumulation of data is easy.

• Measurement with Auto Wavelength Switching
  Multi Wavelength Measurement Mode
  Prepare multiple wavelengths to measure, then press a button.

Multi Wavelength Measurement is a mode in which multiple specified wavelengths from the same optical port are measured automatically in order. You can also specify to perform analysis or file saving as needed for each measurement.

• Macro’s with Predefined Procedures –One Button Mode
  Simply choose previously set measurement procedures, then press a button.

You can execute up to five saved measurement procedures in order. A batch of measurement procedures can be run directly from the main menu. Measurement and analysis conditions can be read from a file, making it easy to set up the measurement procedures.

• Measurement Wizard –Assistance setting up measurements

Displays detailed explanations of parameters in the measurement conditions setting menu, and gives guidelines for setting methods. This function assists unskilled users.

• ACTIVE LINE ALARM –Checking for communication lightNever disturb communication lines

There may be concern that technicians inputting the OTDR measurement signal into the communication line could cause communication errors. The live line alarm monitors the fiber’s optical power level and diplays an alarm message if it detects optical power at or higher than a specified threshold level, in order to warn the technician not to mistakenly feed the signal into the communication line.

• Plug Check Function –Checking the connection with the OTDR
  Never spoil measurements with poor connections or dirty plugs

The plug check function monitors the condition of the OTDR’s optical input/output connectors and displays an alarm if the connection is not properly made. This function is useful for checking for damage, dirt, or other problems with optical plugs at the OTDR or on the fiber under test, and for helping technicians to remember to connect the fiber under test.

• Detecting Abnormal Events –Fault Event Display Function

The fault event display function detects abnormal connection or reflection points and displays them. Of the events detected by the event detection function, abnormal events that cross a specified threshold value are highlighted in the event table and waveform display.

• Measurement with Comparison to Reference Waveform –Trace Fix Function

You can freeze the display of one trace and overlap it with real time or averaged waveforms for comparison. This is useful to create a template when installing multicore fiber, or for checking aged deterioration during maintenance on existing fiber networks. In addition to the last-measured waveform, a waveform can be loaded from a file to be used as the reference waveform.

• SETUP KEY –Jump to measurement condition setting menu

With the new SETUP button on the front panel, it is easy to move to the measurement condition setting menu.

• Smart File Function

Because the AQ7270 makes it easy to differentiate between measured optical fibers—even complex ones—you can add arbitrary information to file names such as measured wavelength, ID number, tape number, or comments. You can also have the ID number or tape number automatically updated and saved after each measurement.
Trace data can be saved in SOR and CSV format. Also, you can save screenshots as BMP, JPG, or PNG files. TRB or TRD files saved on Yokogawa’s previous AQ7250 and AQ7260 models can also be loaded.

• USB Function

USB connectivity makes it more convenient to output to external memory or printers, and to set up communication. The AQ7270 comes standard with two USB1.1 compliant connector ports (Type A and Type B).

 

• AQ7932 is application software that performs analysis of trace data measured by the AQ7270 OTDR on a PC, and creates reports. The report creation wizard makes this task simple. AQ7270 OTDR data can be easily loaded onto a PC using USB memory or the communication interface. Measured Data Analysis and Report Creation Tool AQ7932 OTDR Emulation Software (Sold Separately) Note Operating System: Microsoft Windows 2000, XP Excel: Microsoft Excel 2000, XP, 2003

• Trace Analysis

You can edit event search conditions, approximate curve line settings, and other conditions, and then repeat the analysis. And now it is even easier to operate; simply click the function icon with the mouse.

• Analysis Functions

Display up to eight traces on screen and perform a variety of different analyses including: multi trace analysis, differential trace analysis for comparing recent waveforms with old ones, and 2 way trace analysis function for analyzing average values of data measured from both directions in the optical fiber.

• Creating Reports

Compiles trace and measured values from trace files and creates a report. Reports can also be created in Excel or CSV format. Reports are easy to create by following the step-by-step instructions in the report wizard.
