Yokogawa Test & Measurement Spectrometer AQ6370D

Thread Content

　　Yokogawa's spectrometers feature high quality and advanced technology, offering top-tier reliability and flexibility. The design of these products meets the performance requirements for research and development, testing, and production. For over 30 years, the YOKOGAWA (formerly Ando) spectral analyzer OSA has been widely used in telecommunications, active device development, passive device development, and numerous fields that utilize light sources. 　　Today, we’re going to introduce the Yokogawa spectral analyzer AQ6370D! 　　 　　The spectral analyzer AQ6370D boasts world-class optical performance: Wavelength range: 600~1700nm ； High wavelength accuracy: ±0.01nm ； High wavelength resolution: 0.02nm ； Large dynamic range: 78dB (typical value) ； Wide power range: +20~-90dBm ； Fast measurement: 0.2 seconds (100nm span) ； Suitable for single-mode and multi-mode fibers. 　　The AQ6370D spectrometer is available in two versions: the standard version and the high-performance version. The high-performance version offers higher wavelength accuracy and a larger dynamic range. High wavelength resolution: 0.02nm. High wavelength accuracy: ±0.01nm. High-performance version: ±0.01nm (C band); standard version: ±0.02nm (C+L bands). Peak value accuracy of ±1.0nm, resolution setting of 0.05nm; large dynamic range measurement mode available in the high-performance version. The AQ6370D spectrometer features steeper filtering edges. The high-performance version AQ6370D also offers a larger dynamic range, within 0.2nm of the peak wavelength. The steeper spectral characteristics of a monochromator enable the effective separation of highly similar spectral signals and precise measurement. 　　 　　Spurious light suppression rate: 80dB (typical value). This new specification provides spurious light suppression, thereby eliminating the need for a large-dynamic measurement mode with a slower scanning speed. The AQ6370D features a high stray light suppression rate, which can significantly reduce measurement time. 　　Wide power range: +20dBm to -90dBm. The AQ6370D can measure high-power light sources such as pump lasers for optical amplifiers and Raman amplifiers, as well as weak light signals. Depending on the requirements of the test application and measurement speed, the measurement sensitivity can be selected from 7 categories. 　　(1) Improved power sensitivity: -85dBm (1000–1300nm) 　　(2) Smoothing function – reduces noise in the spectrum being measured 　　(3) Large dynamic range measurement mode – stray light can occur when a strong light signal is input; by reducing the impact of this stray light, a larger dynamic range can be achieved. 　　Free-space input: The AQ6370D 4 OSA can handle both multimode and single-mode fibers simultaneously; when working with multimode fibers, its low insertion loss helps to maintain excellent measurement efficiency. 　　The insertion loss of the input connector varies little: this improves measurement repeatability. 　　Non-physical connection: It does not damage the fiber optic cable. 　　APC power compensation: The APC power compensation function can be used to adjust the power deviation caused by the insertion loss of the APC connector. 　　Excellent efficiency Rapid measurement: 0.2 seconds/100nm: Thanks to advanced monochromators, faster circuits, and noise reduction technologies, the AQ6370C can complete measurements over a 100nm wavelength range in just 0.2 seconds, whether it’s dealing with steep-spectrum signals from DFB-LDs or DWDM sources, or with low-power signals from broadband light sources. 　　Fast remote interfaces (Ethernet, GP-IB) Wide-range, high-resolution scanning: While maintaining high wavelength resolution, a single scan can cover up to 50,001 data sampling points. This is simpler and more efficient than the measurement in traditional systems. 　　Simple to operate 　 Curve zooming function: Clicking and dragging the mouse allows you to change the display parameters, such as center wavelength and span ； You can immediately zoom in on the area of interest and move it around as you wish. 　　Mouse & keyboard operation: (1) The front panel is intuitive, making it easy for users to operate. (2) The mouse makes operations simpler. (3) Labels and file names can be entered using the keyboard. 　　Simple data processing 　USB storage: The USB interface supports large-capacity mobile storage and hard drive storage. 　　512MB of memory: capable of storing over 20,000 waveform datasets. Function to save multiple curves at once: allows 7 curves to be saved in one file immediately.
