- Various alarm and error measurements
Alarms and errors are generated in a variety of modes for SONET/SDH/OTN frames. For alarm and error measurements, status and measurement results are displayed.
- Bit error (BER) measurement
Bit errors in the payload and non-frame bit errors at 40/43/44 Gbit/s can be measured in addition to the parity errors in the overhead.
- Delay time measurement
A transmission delay time from the signal transmission through the DUT to the return can be measured at a resolution of 0.1 μsec.
- Multiple measurements
Not only OTN frames but also mapped multiple channels can be measured at the same time.
- Frame editing
The overhead of the SONET/SDH frame and OTN frame can be freely edited.
Frame monitoring
The overhead and payload of the SONET/SDH frame and OTN frame can be monitored.
Trace message
The trace message of the section (J0) and Path (J1) can be edited, and the trace message in a received frame can be monitored and displayed. Various trace messages of the OTN frame can also be edited and monitored.
- Stress-free operation
Reduces the setup time and contributes to a reduction in the turn around time for automated systems.
- Direct operation with touch panel
- Large 10.4-inch display
- USB Interface
- Large Hard Drive capacity

Built for 40G Next Generation Networks, the NX4000 is designed to measure the
transmission and reception of communication frames, alarm/error characteristics,
and the transmission characteristics, such as the transmission delay time, of 40
Gbit/s SONET/SDH/OTN networks. The NX4000 supports multiple optical
modulators and wavelength tunable transponders providing measurement
solutions tailored to the needs of customers. In addition, the NX4000 can also be
used to measure non-frame signals.

| Building Automated Test Systems |
| The AQ6375 is equipped with GP-IB, RS-232, and Ethernet (10/100Base-T) interfaces to be connected with
an external PC for remote access and building an automated test system. Macro Program is a useful built-in
function for making a simple auto test program. |
| Compatible with SCPI |
| The standard remote commands of the AQ6375 are
compatible with SCPI, which is an ASCII text based
standard code and format that conforms to IEEE-
488.2. |
| AQ6317 Emulation Mode |
| The AQ6375 supports private remote programming
codes of Yokogawa's best selling AQ6317 series for
users to easily upgrade from their current
automated test environment.
(Note. some commands may not be compatible due to changes
in specifications and functions.) |
| Macro Programming |
| Macro programming enables user to easily create
test procedures by recording the user’s actual key
strokes and parameter selections. An external PC is
not required because the macro program can also
control external equipment through the remote
interfaces. |
AQ6375 Viewer
Emulation and Remote Control Software (Optional) |
 |
AQ6375Viewer is PC application software designed to work with Yokogawa’s AQ6375 Optical Spectrum Analyzer. |
| Emulation |
| The software has exactly the same user interface
and functions as the AQ6375 so that you can easily
display and analyze waveform data. |
| Remote Control |
| \Allows to control AQ6375 from anywhere on the
Ethernet network. Because of fast data transfer
speed of Ethernet, measurement data can be
updated in real time.
Note. the data update speed varies depending on network
performance and conditions. |
