Ando optical spectrum analyzer AQ6331 osa yokogawa
Ando Optical Spectrum Analyzer AQ6331 OSA Yokogawa NR!
Physical Condition: Unit is in fairly poor condition. It is missing a rubber corner piece on the front right, and the help button is gone. The casing has a lot of scuffs. The back of the unit is missing most of its screws, and the S/N tag was half removed to get at the screw underneath. The metal is bent on the back top sides. On the bright side, the screen is in good condition, all of the other buttons are intact and the dial knob is intact and functional. Please look at the photos below.
Functionality: Unit powers on and we were able to navigate using the on-board controls. We were also able to hook in an external keyboard and mouse, and the unit responded to F-key commands as well as moving through the menu when "M" is pressed, reponding to the ALT key and the ESC key... the mouse worked great, and we were able to scoot around the screen and click on everything. As mentioned, the printer works. We were also able to access stored images on the unit (stored by the previous owner) and after a lot of poking around, we were able to get the unit to display traces. Please see photos below for samples of the screens. There is no paper for the printer, so it is untested. We don't really have the equipment or the knowledge to be able to give this unit a complete and comprehensive test, so we can't guarantee that it is going to be 100% functional. Feel free to request specific information; we will do our best to accommodate your requests.
The AQ6331 is a portable optical spectrum analyzer (OSA) with the high performance required for 50 GHz and 100 GHz DWDM network testing, in both the C and L bands. The AQ6331 is compact, yet has all the features required for DWDM system evaluation. Further, it has excellent wavelength resolution, with accuracy and dynamic range equal to that of any conventional bench-top OSA used in research and development applications. The AQ6331 OSA is suitable both for the installation and maintenance of DWDM systems and for research and development applications.
Features ±0.02 nm wavelength accuracy at 1520 to 1580 nm and ±0.05 nm accuracy at 1580 to 1620 nm, using an internal light source to perform wavelength calibration.
* Internal wavelength calibration function
The built-in reference light source eliminates the need for an optical fiber connection to an external light source to perform wavelength calibration. Connection to the reference light source is done automatically by an internal optical switch.
* High dynamic range and high wavelength resolution
With dynamic range of 55 dB or more (peak ±0.4 nm) and wavelength resolution of 0.05 nm (min.), 50 GHz channel-spaced DWDM systems can be measured.
Optical amplifier output and high output laser diodes in DWDM systems can be measured directly because the measurement level can range up to +20 dBm.
* Low polarization dependency
Optical amplifier gain can be measured accurately because polarization dependency is as low as ±0.05 dB.
* Long-term analysis function
Changes to each DWDM channel peak can be measured over time.
* Convenient programming function
Shortens measurement time because measurement conditions and processes, etc., can be input to memory prior to measurement.
* Individual traces of three wave-forms
Individual traces of three waveforms can be displayed. Can also compare two waveforms - a reference waveform and a measurement result - to determine the difference between the each.
* Internal high-speed printer
Yokogawa Electric Corporation and Ando Electric Co., Ltd. have merged. Ando optical fiber test equipment, optical measuring instruments, and wireless communications equipment have been transferred to Yokogawa.
