Here is the feature description of the AQ6370D optical spectrum analyzer:

  1. High - Performance Optical Measurement
    • Wide Wavelength Range: It covers a wavelength range from 1200 nm to 1650 nm, which is suitable for various optical communication and optical device testing applications in the near - infrared band.
    • Good Wavelength Resolution: The instrument provides a relatively high - resolution measurement. The typical wavelength resolution can reach 0.05 nm (50 pm), which allows for detailed analysis of the spectral characteristics of optical signals and can distinguish closely spaced spectral components.
    • High Wavelength Accuracy: With a high - accuracy wavelength measurement function, the wavelength accuracy is within ±0.05 nm in the C - band and ±0.1 nm in the S - band and L - band. This ensures accurate positioning and measurement of the wavelength of optical signals, which is crucial for applications requiring precise wavelength control.
    • Wide Dynamic Range: The AQ6370D has a wide dynamic range, which can reach 60 dB or more. This enables it to measure optical signals with large power differences at the same time, from weak optical signals to strong optical signals, without losing measurement accuracy.
  2. Sensitivity and Noise Performance
    • High Sensitivity: It has a high - sensitivity detection module, which can detect very weak optical signals. The minimum detectable optical power can reach -90 dBm or lower, depending on the specific measurement conditions and resolution settings. This high sensitivity is beneficial for measuring the characteristics of optical devices with low output power or the loss of optical fibers and components.
    • Low Noise Floor: The instrument has a low - noise design, and the noise floor is relatively low. This helps to improve the signal - to - noise ratio of the measurement results, making the measured spectral data more accurate and reliable, especially when measuring weak signals.
  3. Measurement Speed and Stability
    • Fast Measurement Speed: The AQ6370D can complete spectral measurement within a short time. The typical measurement time is within a few seconds to tens of seconds, depending on the measurement range and resolution. This fast measurement speed is beneficial for improving the efficiency of optical device testing and research and development, allowing for rapid acquisition and analysis of spectral data.
    • Good Stability: The instrument has good long - term stability. Through a stable optical path system and electronic control circuit design, it can maintain accurate and reliable measurement results during long - - term continuous use, reducing the influence of environmental factors and instrument self - drift on the measurement results.
  4. User - Friendly Interface and Functions
    • Intuitive Display: It is equipped with a clear display screen, which can intuitively display the measured optical spectrum curve and relevant measurement parameters. Users can easily read and analyze the spectral data through the display screen, and can also perform simple operations such as zooming and panning of the spectrum.
    • Built - in Analysis Functions: The AQ6370D has a variety of built - in analysis functions, such as automatic peak detection, wavelength calibration, power integration, and spectral bandwidth calculation. These functions can help users quickly and accurately obtain the key parameters of the optical spectrum, saving time and effort in data processing.
    • Data Storage and Communication: The instrument supports data storage, which can save the measured spectral data and measurement parameters for subsequent review and analysis. In addition, it is also equipped with communication interfaces such as USB and Ethernet, which can be easily connected to a computer or other external devices to realize data transfer and remote control.
  5. Optical Input and Connection
    • Single - Mode Fiber Input: The optical input of the AQ6370D uses a single - mode fiber interface, which is compatible with standard optical fiber connectors such as FC / PC and SC / PC. This ensures good optical coupling efficiency and signal transmission quality, and is convenient for connecting with various optical devices and optical fiber systems.
    • Low Reflection Design: The optical input port of the instrument adopts a low - reflection design to reduce the influence of optical reflection on the measurement results. This is very important for measuring optical devices and systems that are sensitive to reflection, such as lasers and optical filters, which can avoid measurement errors caused by reflected light.
