What brand and model is better to use for network analyzer now?

<> UV-2000 high-intensity ultraviolet analyzer is a new generation of analytical instruments successfully developed by Shengwei, with high sensitivity, easy to use, especially the use of 302nm wavelength to the sample damage effect is smaller, it can be applied to the observation of DNA, RNA electrophoresis gel samples, can detect proteins, nucleotides, etc., in the manufacturing industry to check the quality of hormone alkaloids, vitamins and other fluorescence, plays an important role in the analysis of thin layers.

Scope of application: The ultraviolet lamp, color filter and color filter used in our factory have been precision processed and of good quality, so the ultraviolet output of this instrument is strong and uniform, which can greatly shorten the time of shooting samples, and the negative film is clear and free of stray background light.

This product has high sensitivity, easy to use, especially the use of 302nm wavelength to the sample damage effect is smaller, is the ultraviolet analyzer of the updated product, the use of fully enclosed high-quality metal chamber, no need to operate in the dark room, easy to use, simple to operate, the instrument can be installed digital camera, easy to shoot and take pictures, suitable for DNA, RNA gel, protein gel; Thin layer chromatography is an indispensable analytical instrument for teaching and scientific research units such as molecular biology research and identification.

The instrument is equipped with a set of transmitted ultraviolet light sources for observation, analysis and photography. And specially designed a dark box, the user does not need a dark room, can observe and analyze the sample, the dark box is equipped with a special camera installation device, the dark box observation room is equipped with anti-ultraviolet glass, it filters out more than 95% of ultraviolet rays. The rubber tapping window and observation port are designed on both sides of the instrument box to facilitate the segmentation of nucleic acid samples.

Ultraviolet transmission 302nm; A set of incandescent lamps.

A vector network analyzer that comes with a signal generator that can perform a frequency sweep on a frequency band. In the case of a single-port measurement, the impedance or reflection can be determined by adding an excitation signal to the port and measuring the amplitude and phase of the reflected signal. In the case of dual-port measurements, transmission parameters can also be measured.

Because it is obviously affected by distribution parameters, etc., the network analyzer must be calibrated before use.

A network analyzer is a comprehensive microwave measurement instrument that can perform scanning measurements over a wide frequency band to determine network parameters. The full name is Microwave Network Analyzer. The network analyzer is a new type of instrument for measuring network parameters, which can directly measure the complex scattering parameters of active or passive, reversible or irreversible dual-port and single-port networks, and give the amplitude and phase frequency characteristics of each scattering parameter in a swept manner.

The automatic network analyzer can correct the error of the measurement results point by point, and convert dozens of other network parameters, such as input reflection coefficient, output reflection coefficient, voltage standing wave ratio, impedance (or admittance), attenuation (or gain), phase shift and group delay and other transmission parameters, as well as isolation and directionality.

The network analyzer is a new type of instrument for measuring network parameters, which can directly measure the complex scattering parameters of active or passive, reversible or irreversible dual-port and single-port networks, and give the amplitude pin detection and phase frequency characteristics of each scattering parameter in the form of frequency sweep. The automatic network analyzer can correct the error of the measurement results point by point, and convert dozens of other network parameters, such as input reflection coefficient, output reflection coefficient, voltage standing wave ratio, impedance (or admittance), attenuation (or gain), phase shift and group delay and other transmission parameters, as well as isolation and directionality.

Generally speaking, it is often used in companies such as meta-book devices or systems composed of various components, such as: antennas, cables, RF circuits, filters, couplers and other industries!
