Is an indispensable network analyzer you are right?

The network analyzer is a powerful test measurement instrumentation, as long as the traffic is properly used and operated, it can achieve extremely high precision, which compares and measures other electronic devices, electronic components by using its own signal source. Electrical characteristics and performance parameters such as electronic parts, network connections, cable lines meet standards and requirements, and accurately measure amplitude and phase information in incident waves, reflected waves, transmission waves, and describe the device under test by ratio measurement. Reflection and transmission characteristics. Its application is very wide, is indispensable in many industries, especially in the measurement of wireless radio frequency (RF) components and linear characteristics of the equipment. The price of a network analyzer is usually more expensive. For novices, how to properly use the noodle meter during the test, avoiding instrument damage is a very important thing. Today, Ante Tesch will be briefly introduced to the online analyzer's precautions, I hope to help everyone: 1. When testing the product, you cannot directly power the test. 2, before testing the power amplifier, you must detect no self-excitement on the spectrum instrument to test other indicators. 3. Prevent large DC electricity, the network is maximized to withstand 10V direct current. 4. Prevent the input of the signal. (1) The maximum allowable input signal of the network analyzer is 20 dBm. (2) When the input signal is greater than 10 dBm, the corresponding attenuator should be added. 5. Ensure that the instrument is used before use. Under the premise of proper use, it is some of the most accurate radio frequency instruments, typical precision is ± 0.1 dB and ± 0.1 degrees. It can perform accurate, repeatable RF measurements, provided by the configuration and measurement ability like their application range. Choose suitable instruments, calibration, functions, and adopt a reliable RF measurement method to optimize your test results. Reprinted from the electronic engineering network.
