New Features
Purge feature
Due to the high resolution and sensitivity of the AQ6375E, it can actually detect the presence of water molecules in the air. The water vapor is detected in the upper Near-IR wavelength region and could overlap with or mask the spectral characteristics of the actual device under test in that particular region.
By continuously supplying a pure purge gas such as nitrogen to the monochromator through the ports on the back panel, the AQ6375E can reduce the influence of water vapor absorptions and provide more reliable and accurate measurements than ever before.
Built-in cut filter for high order diffracted light *
Due to the diffractive technology used, the monochromator in some circumstances could generate high order diffracted light, which appears at wavelengths equal to the integral multiple of input wavelengths.
By cutting incoming light below 1150 nm with the built-in filter, the AQ6375E drastically reduces the influence of high order diffracted light on the measurement. Thus, the measured data are always reliable and replicate the real signal under test.
* Except Limited model
Double speed mode
Increases the sweep speed up to 2 times compared to the standard sweep mode, with only a 2 dB penalty to the standard sensitivity value.
Long Wavelength Range: 1200 to 2400 nm [Standard, and Limited], 1000 to 2500 nm [Extended ]
The AQ6375E covers not only the wavelength span used in communications, but also the 2µm region which is used for environmental sensing, medical, biology and industrial applications.
High Sensitivity: down to -70dBm *
The AQ6375E can measure optical power from +20dBm down to -70dBm thanks to its high-dynamic and very low noise components and circuits used for photo detection. This enables precise measurements of both high power and low power sources.
Measurement sensitivity can be chosen among 7 values according to the measurement speed required by the specific test to be performed.
*Except Limited model
High Resolution & Wide Dynamic Range *
The AQ6375E uses a double-pass monochromator structure to achieve high wavelength resolution (0.05 nm) and wide close-in dynamic range (55 dB). Thus, closely allocated signals and noise can be separately measured.
*Except Limited model
High speed Measurement
GREATER EFFICIENCY
High Speed Sweep
With a proprietary sweep technique the AQ6375E achieves a much faster sweep speed than conventional measurement systems, which use a monochromator. Max. sweep time is only 0.5 sec. for 100 nm span.
Fast command processing and data transfer
Applying a fast microprocessor, the AQ6375E achieves very fast command processing speed and Ethernet interface provides up to 100 times faster data transfer speed than GP-IB.
Fast auto-calibration
The calibration and alignment process takes less on the unit take than 2 minutes and is fully automatic.
Free-Space Optical Input
The AQ6375E uses a free-space optical input structure, i.e. no fiber is mounted inside the instrument.
This smart solution is:
- WORRY-FREE, as no internal fiber can be scratched or get dirty
- MAINTENANCE-FREE, as no internal fiber has to be cleaned
- VERSATILE, as the instrument accepts both /PC and /APC connectors
- DUAL PURPOSE, as the instrument accepts both Single-Mode and Multi-Mode fibers without being affected by the high insertion loss from MM-SM fibers matching
DUT-oriented test apps simplify the test process
The appplication mode (APP) transforms an OSA into a versatile machine dedicated to a device under test (DUT). APP mode provides a DUT-specific user interface that navigates the user from configuration settings to test result output without worrying with other OSA settings. The AQ6375E comes pre-installed with several standard applications including DFB-LD testing, FP-LD testing and SC light source testing. Additional optional applications are available for download from the Yokogawa Test&Measurement website.
