FAST MEASUREMENT

New High Sensitivity ModeThrough newly developed noise reduction techniques, the AQ6370 can complete a measurement faster even with a high sensitivity setting. This is imperative when measuring weak signals. A new sensitivity mode make sit up to five times faster*.

 

 

Quick Key ResponseApplying a faster microprocessor and new algorithms, key response time and initial hardware setup time before a sweep is drastically reduced. The new system achieves up to one hundred times faster response*.

 

 

 

 

 

FAST DATA TRANSFER AND STORAGE

ETHERNET provides up to one hundred times faster data transfer speed than the GP-IB data transfer*.

 

GP-IBprovides up to ten times faster data transfer speed than the conventional GP-IB*.


USBprovides up to ten times faster data recording/retrieving speed to a removable memory device than the floppy disk*.

 

SATISFACTION WITH SINGLE MEASUREMENT

With the increased number of data sampling points (max 50,001), the AQ6370 can measure a wider wavelength range (span) with higher resolution. Single sweep can complete the test that took three sweeps in the past*.

 

 

 

 

Expedites Development of Automated Test Systems

The AQ6370 is equipped with two GP-IB, RS-232C, and Ethernet (10/100BASE) interfaces to be connected with an external PC for remote access and building an automated test system. It is compatible with a standardized programming language and supports AQ6317 commands for easy programming. Macro Program is a useful built-in function for making a simple auto test program.

COMPATIBLE WITH SCPI

SCPI is an ASCII text based standard code and format that conforms to IEEE-488.2. The standard remote commands of the AQ6370 are compatible with SCPI. It can be used with most computer test languages and test application software.

AQ6317 EMULATION MODE

The ANDO AQ6317 series is Yokogawa’s best-selling optical spectrum analyzer. Since there are so many existing users all over the world, the AQ6370 supports private remote programming codes and formats of the AQ6317 series to make it easier for users to upgrade their current test environment.

Note: some commands may not be compatible due to changes in specifications and functions.

MACRO PROGRAMMING

Macro programming enables the user to easily create test procedures by recording the user’s actual key strokes and parameter selections. One program can contain up to two hundred program lines, and programs can be called as subroutines to make the main program simple. Moreover, macro programs can control external equipment through Ethernet, RS-232C and GP-IB port (GP-IB2). Therefore, an external PC is not required to build a simple auto test system.

LabVIEW® DRIVER SUPPORT

LabVIEW® is a popular test application software. Yokogawa can provide users with LabVIEW drivers for the AQ6370.
Note: LabVIEW is a U.S. registered trademark of National Instruments.

Enhances User Friendliness

INHERITS PROVEN OPERABILITY

The AQ6370 inherits front panel operation and function key assignments from our conventional models that are proven intuitive and easy to use by our multitude of users.

MOUSE & KEYBOARD OPERATION

You can easily operate the AQ6370 with only a mouse instead of the front panel keys. Measuring conditions displayed on the trace screen can be changed directly by the mouse pointer. The keyboard is useful for entering labels and file names.

The functions of panel keys appear by clicking right mouse button. The functions of panel keys appear by clicking right mouse button.

Direct parameter entry
Arrow pointer transforms into finger pointer when you move it to parameters.

 

TRACE ZOOM CAPABILITY

Trace zoom makes it possible to change display conditions, such as center wavelength and span, by clicking and dragging the mouse to select the designated area to enlarge. No need to make another sweep to refresh the display conditions anymore. The analysis function can be performed in the enlarged area.

 

 

Overview Window
Once the trace is zoomed in, the overview window appears and shows the entire trace. By dragging the zoomed area border in this window with the mouse, the display area in the main trace window can be modified.

 

 

 

In the Analysis Screen,traces can also be zoomed. When a line item on the analysis result table is selected, the display area is automatically shifted and the corresponding signal is centered in the display area. This makes it easier to verify the accuracy of the analyzed data.

 

Facilitates Frequent Data Handling

 

LARGE INTERNAL MEMORY

The AQ6370 has a 128 MB user area in the internal memory that can save test setups, waveforms, analysis results, and macro program files. It is large enough to save more than five thousand traces.

 

Thumbnail file previewmakes it easy to find a particular file out of thousands of files. (The Thumbnail file preview function also works with an external memory.)

 

 

SUPPORTS USB 1.1 MEMORY

 

 

The AQ6370 has two USB 1.1 compatible interfaces. They support large size removable memory devices such as Flash ROM and hard disk drives (HDD). Removable static memory of more than 1 GB and USB compatible external HDDs of more than 40 GB in capacity are commercially available. (as of January 2006)

 

World Class Optical Performance and Flexibility*

EXCELLENT SIGNAL SEPARATION

The AQ6370 uses a double-pass monochromator structure to achieve high wavelength resolution (0.02 nm) and wide close-in dynamic range (70 dB). Thus, closely allocated signals and noise can be separately measured. OSNR measurement of 50 GHz spacing DWDM transmission systems and EDFA evaluation with multiple wavelength sources can successfully be performed.

Close-in Dynamic Range
70dB at peak ± 0.4nm, resolution setting 0.02nm (typical)

 

WIDE MEASUREMENT RANGE

Power: +20 dBm to -90 dBm
The AQ6370 can measure optical power as high as +20 dBm, which enables direct measurement of high power sources such as optical amplifiers and pump lasers for Raman amplifiers. Measurement sensitivity can be chosen from seven categories according to test applications and measurement speed requirements.

Wavelength: 600 nm to 1700 nm
The AQ6370 covers not only telecommunication wavelengths, but also the visible light wavelength region which is used for home electronics, medical, and industrial material applications.

 

 

Level sensitivity settings;
NORM Hold, NORM Auto, NORM, MID, and HIGH (1, 2, and 3), that correspond to sensitivity from - 60dBm through -90dBm.

High dynamic range mode settings;
CHOP and SWITCH
Modes used to obtain a better dynamic range by reducing an influence of stray-light. They are applicable in MID and HIGH mode.

 

 

MULTIMODE FIBER TEST CAPABILITY

The AQ6370 uses a free space input structure that can handle up to GI 62.5/125 multimode fiber on the same interface that supports single mode fiber.  Multimode fiber is commonly used in high speed Ethernet network, such as GE-PON.
The free space input is also beneficial for measurement repeatability as insertion loss variation at the input connector is smaller than the other input type which has an optical fiber inside the monochromator.

 

 

 

PULSED LIGHT MEASUREMENT CAPABILITY

The AQ6370 can catch the peak power of a pulsed signal using PEAK HOLD or using an externally provided trigger to synchronize with the measured signal. It can be applied to the transmission loop testing of telecommunication systems, and also to the low power measurement at the early stage of laser chip development since it works in the high sensitivity modes.

Real-Time Remote Operation for Monitoring and Troubleshooting

Optional Application Software

AQ6370Viewer is PC application software designed to work with Yokogawa's AQ6370 Optical Spectrum Analyzer. It has exactly the same user interface and functions as the AQ6370 so that you can easily display and analyze waveform data acquired by the AQ6370.

Remote control function

The remote control allows you to control AQ6370 Optical Spectrum Analyzer from anywhere on the Ethernet network. This gives you the sensation of setting measurement conditions and analysis parameters, and executing measurement on an actual unit. Because of fast data transfer speed of Ethernet, measurement data can be updated in real time. It is useful for diagnosis of trouble in production lines, periodical observation of long term tests in the lab, and other applications. Note: the data update speed varies depending on network performance and conditions.
