/div> & nbsp;& nbsp;& nbsp;& nbsp; In the field test, the failure of cables, connectors, antennas and other components or signal interference and other RF problems will affect the successful installation and maintenance of the RF system, which will lead to the decline of network performance, and even reduce revenue. Therefore, the test of RF problems is very important. In general, large and bulky desktop instruments are required to perform such tests. Field engineers and technicians have to transport them to the site, especially in harsh or extreme environment (such as the top of transmission tower). Once on site, they also have to set up the instrument to perform the measurement correctly, which may take a lot of time. In fact, field engineers and technicians sometimes spend more time on instrument setting than on specific measurement, which greatly affects the speed, efficiency and flexibility of measurement. To meet the challenge of RF measurement, we need a handheld solution with the advantages of fast, efficient, accurate and easy to use.
 
 & nbsp;& nbsp;& nbsp;& nbsp; Identify the best solution
 
 & nbsp;& nbsp;& nbsp;& nbsp; Handheld spectrum analyzer can provide field engineers and technicians with the required performance and functions, and help them successfully complete the field measurement of RF and microwave equipment (such as transmitter and component testing, receiving path signal monitoring and antenna tuning) and RF environment (such as band gap, signal coverage and interface search), so it is an ideal solution to solve the above problems. For field engineers and technicians, these measurements are very important for RF system installation, field maintenance, potential problem diagnosis, spectrum monitoring and interference detection.
 
 & nbsp;& nbsp;& nbsp;& nbsp; The best handheld spectrum analyzer must have the following characteristics at the same time, namely, ruggedness, simple operation, various user-defined functions, ergonomic characteristics and the ability to perform accurate measurement. In order to ensure durability in harsh field environment, the construction of handheld analyzer must be very strong. That is to say, it must adopt a fanless design, as well as a rugged chassis and interface, so as to be able to ensure measurement integrity without being affected by environmental changes
 
 & nbsp;& nbsp;& nbsp;& nbsp; Excellent ease of use can directly meet the needs of field engineers and technicians, so that they do not need to perform complex instrument settings, and can make full use of the built-in functions and optimization functions that significantly expand the use of the instrument, thus improving the measurement efficiency. Many practical features of the analyzer, such as the intuitive user interface, ergonomic design, the "visibility" of the display screen and customized or personalized functions, are the key to achieve this goal.
