Yokogawa / Ando AQ6140 Multi-Wavelength Analysis Meter

  • Complete Wavelength Analysis in D-WDM Systems
  • Measures up to 256 Channels Simultaneously
  • Highly Accurate Wavelength Measurement
  • High Resolvable Separation
  • Grid Monitoring Function
  • Drift Measurement Analysis
  • 6.5 Inch Color LCD and VGA Monitor Interface
  • Remote Interfaces: GPIB and RS-232


The Yokogawa / Ando AQ6140 / AQ6141 series of multi-wavelength meters are ideal for wavelength analysis in D-WDM (dense-wavelength divided multiplex) Systems.

The AQ6140 measures both wavelength and power up to 256 channels, and displays waveform and measurement result at a time. Capable of checking if it’s matched to advice of ITU-T and severe monitoring of grid. Also capable of displaying the list of peak wavelength and power.

Long-Term Function
Displays changes of peak wavelength and power of one channel.
Displays not only current measurement result but also maximum rate, minimum rate or balance of maximum rate and minimum rate below the waveforms.

Grid Monitoring Function
Analyzes peak wavelength of set grid.
Searches peak wavelength, or analyzes wavelength gap and changes of power within the grid.

Standard Screen Display Mode
The waveform and the peaks are display simultaneously on the screen.
It is used to monitor WDM system temperature characteristics and evaluate laser oscillators.

List Screen Display Mode
This mode displays a list of the peak wavelengths, up to 14 at a time.

3-d Screen Display Mode
Displays 3D waveforms and peak lists at a time. It helps to check the change of measurement result by time.

Marker Screen Display Mode
The marker function simplifies tasks such as analysis of wavelength and power level difference.

Product Family: AQ6140, AQ-6140, AQ 6140

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!

InstraView Request Form

To get started:

  1.   Fill in the request form below
  2.   We'll send you an email letting you know exactly when your piece of equipment will be available for viewing
