Directional power meters are used to measure power and reflection under operational conditions. They are connected between source and load and measure the power flow in both directions. The power applied to the load and the reflection can thus be measured. Typical applications are in installation, maintenance and monitoring of amplifiers, transmitters, antennas and RF/microwave generators in industrial and medical fields.

Customers looking for a general purpose spectrum analyzer will appreciate the flexibility of the ESA spectrum analyzer that can be used for a wide range of applications from aerospace and defense to the manufacturing line. Browse the ESA Brochure.Customers who wish to take advantage of the ESA flexibility but who need a faster analyzer for the manufacturing line, or connectivity to LAN/USB in addition to GPIB, or want to do in depth signal analysis with 89600 VSA software will benefit from the new EXA signal analyzer. The EXA signal analyzer now comes standard with many of the ESAs optional features and yet offers more applications than the ESA. Migrate from ESA to EXA.

Domestic instruments have a low market share in scientific research and teaching instruments

In recent days, the National Science Instrument Industry Development Report (2014) released by the state concluded that domestic scientific instruments are mainly used in inspection institutions of production enterprises, government grassroots inspection units and third-party professional testing institutions. The proportion of scientific research and teaching is only 22.3%. This data indicates that domestic instruments have a low market share in scientific research, research and development and teaching instruments. The report also stated that excellent domestic scientific instrument manufacturers should pay full attention to this market, because researchers and students represent the future instrument market. We must do the following four aspects to promote the healthy development of the domestic equipment industry:

The first is to improve quality. For a long time, when talking about domestically produced equipment, the impression is that 'the stability is poor, the failure rate is high, and the test results are not stable enough', which becomes the biggest constraint for using domestically produced instruments.

The second is to break through the monopoly. According to the data, China imported 6.294 billion US dollars of experimental analytical instruments in 2013, with exports of 1.456 billion US dollars and a trade deficit of 4.838 billion US dollars. From 2009 to 2013, the deficit has been expanding. High-end equipment such as ICP, mass spectrometry, scanning electron microscopy, and X-ray fluorescence spectrometry can only rely heavily on imports due to monopoly.

The third is technological progress. The low-end products are complete in variety, and high-end products cannot be produced, resulting in domestic manufacturers only able to compete at low prices to seize the market. For example, the price of high performance liquid chromatography produced in China is only 100,000-150,000 yuan, and the price of imported equipment is at least 300,000 yuan. Therefore, we must make a fuss in the field of high-end new technologies.

The fourth is to cross the monopoly. The invisible technical barriers are mainly manifested in two aspects. First, developed countries have adopted the guise of safety, health and environmental protection, and have established strict technical regulations on commodities, resulting in the use of large instruments with higher detection limits and higher sensitivity for laboratory testing. .

In the final analysis, scientific instruments are equivalent to the 'hidden' military industry, and are the industry sectors that all countries must fight for. The level of innovation, manufacturing and application of scientific instruments reflects the technological and industrial strength of a country and the overall strength of the country.
