How does the audio analyzer test circuit parameters?
- Generally speaking, an audio analysis instrument with complete functions should be able to measure parameters such as signal AC and DC voltage, signal frequency, harmonic distortion, signal-to-noise ratio and so on. Powerful audio analysis instrument provides spectrum analysis, 1/3 octave analysis, octave analysis, sound pressure level measurement, and other functions. If you want to build an audio analysis system, you also need a standard audio generator as the source of the excitation.s
The quality of the coal analysis instrument is the best
- Have a high reputation and credibility in the markets
How do you choose the RTK measuring instrument?
- Our project is to use the "Hua test" i60, that is, look big, all the other good, the function is still very powerfuls
Which UPS power supply is better for analytical instruments?
- Wide input voltage and frequency rangeVery wide input voltage and frequency range, even in the power environment is very bad areas, can also work stably in the city power supply mode, reduce the number of battery discharge, and extend the service life of the battery.s
What is the function of Spectrum Analyzer?
- The spectrum analyzer uses time domain architecture like the appearance of the oscilloscope, as shown in Figure 1.2, panel cloth built many functions of control buttons, as the adjustment of system function and control system, the main function is to display the spectrum characteristics of the input signal in the frequency domain. According to the different spectrum analyzer signal processing method, there are two general types of instant; the spectrum analyzer (Real-Time Spectrum Analyzer) and scan tuning (Sweep-Tuned Spectrum Analyzer) spectrum analyzer.s
How to choose the coal analysis instrument?
- Precautions for coal quality analysis instruments1, shall not flammable, explosive, corrosive substances, or after heating release flammable, explosive, corrosive, volatile substances into the box for heating;2. The relative humidity of heated articles shall not be greater than 85%;3. The drying material needed shall not exceed 70% of the shelf area, and be easy to be ventilated and dried.s
What are the basic structures of spectral analysis instruments?
- A device that provides a continuous spectrum or line spectrum with a high intensity, stability, and small luminous area. The UV light absorption spectrophotometer are commonly used in hydrogen and deuterium lamp light, visible light absorption spectrophotometer used a tungsten lamp and halogen lamp, infrared light absorption spectrophotometer are commonly used silicon carbide, the Nernst lamp light source; atomic absorption spectrophotometer are used hollow cathode lamp.s
How do you review instrument analysis?
- Surface chemical inertness, that is, the surface has no adsorption or poor adsorption, and can not react with the substance under tests
