Optical filter characteristics can be measured from the measured waveforms of the light, from source, going into optical filters, as well as from the measured waveforms of light being output from optical filters. Analysis can be performed not only on optical filters with one mode, but also multimode filters (e.g WDM Filters).

This function is used to measure changes over time in the level of a specific wavelength level. The sweep width is set to 0 nm, and measurement of the single-wavelength light is taken. The horizontal axis is the time axes. It is useful for purposes such as optical axis alignment when a light source is input to an optical fiber.

The template function compares preset reference data (template data) with a measured waveform. In addition, if a function for displaying the target spectrum (target line) on the measurement screen is used, the target spectrum can be referenced while adjusting the optical axis of an optical device.
The Go/No Go test function compares the active trace waveform against reference data (template data) preset by the user, and performs a test on the measured waveform (Go/No Go test).
This function can be used effectively in situations such as pass/fail tests on production lines.

تفسيرها YOKOGAWA AQ6375B Key feature summary:
- Long wavelength range: 1200 to 2400 nm
- Gas purging ports to reduce water vapor effects
- Built-In cut filter for high order diffracted light

- Applicable to single-mode and multimode fibers
- Excellent performance for environmental gas sensing Laser Spectroscopy
- Indispensable tool for R&D and manufacturing of optical devices in the wavelength range from telecom band to 2.4μm
Due to the high resolution and sensitivity of the YOKOGAWA AQ6375B, 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 AQ6375B 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 AQ6375B 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.
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: from 1200nm to 2400nm
The YOKOGAWA AQ6375B 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 AQ6375B 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.
High Resolution & Wide Dynamic Range
The YOKOGAWA AQ6375B 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.
Measured HeNe Laser (1523 nm), Close-in Dynamic range: @ peak±0.8 nm
High speed Measurement
High Speed Sweep
With a proprietary sweep technique the AQ6375B 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 AQ6375B achieves very fast command processing speed and Ethernet interface provides up to 100 times faster data transfer speed than GP-IB.
The calibration and alignment process takes less on the unit take than 2 minutes and is fully automatic.
Free-Space Optical Input
The AQ6375B 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
