Spectral analyzer AQ6370D

spectrum analyzerAQ6374

Product Introduction:

The AQ6374 spectral analyzer covers a wide range of wavelengths from 350 to 1750nm, including visible light (380 to 780nm) and communication fields. The ultra wide measurable power range is -80~+20dBm, with 100001 sampling points and 8 wavelength resolution settings for fast measurement.

Product Features:

*Mouse and keyboard operations

After more than 30 years of user feedback, the front panel is more intuitive and easy to operate. The mouse function makes navigation more convenient, and the keyboard can be used to input numbers and file names.

*Curve amplification function

1) By clicking and dragging the mouse, display conditions such as center wavelength and span can be changed.

2) You can immediately zoom in on the area of interest and drag it freely.

3) No need to modify the display conditions by measuring again.

*Curve calculation and analysis

7 independent curves

Simultaneously display multiple curves;

Calculation between curves

(Subtract two curves);

. Large/small value retention function

*USB port

There are a total of 4 USB ports before and after the instrument, making it easy to connect external devices such as mice, keyboards, external hard drives, and USB drives.

Product application:

1. Testing of related devices

Nowadays, various DFB-LD, FP-LD, and VCSEL light sources that emit visible light to mid wave infrared wavelengths have been widely used in different devices or systems in various application fields, such as telecommunications: glass fiber or plastic fiber optic wiring. Industry: barcode scanner, LiDAR surface scanner. Consumer electronics: Hi Fi audio system audio output, laser printer, computer mouse.

Characteristics of Fiber Bragg Grating

Fiber Bragg Grating (FBG) is a short section of optical fiber with distributed Bragg mirrors, which can reflect specific wavelengths of incident light and propagate only the remaining wavelengths of light. This is achieved by periodically changing the refractive index of the fiber core, which forms a dielectric mirror of a specific wavelength in the fiber core. Therefore, fiber Bragg grating can be used as an embedded optical filter to block specific wavelengths of light, or as a wavelength reflector. The application of fiber Bragg grating is mainly in optical communication systems: it can be used specifically as a notch filter, and can also be used together with optical circulators or optical add/drop multiplexers (OADMs) for optical multiplexers and demultiplexing. In addition, fiber Bragg gratings in the 2-3 μ m wavelength range can also be used as direct sensing elements for strain and temperature sensing in seismic instruments, as well as pressure sensing in harsh environments. To describe the characteristics of FBG, the high wavelength resolution and large dynamic range of AQ6370 series are essential conditions.
