DS31412 is an active feedback spectrum analyzer for cellular systems and is chiefly employed in quality assessment, trial and optimization of such systems. It is a robust, reliable and versatile tool, which is suitable for implementation in any environment, from a drive test to a laboratory.

Applications

DS31412 are used in the evaluation of radio cell and spectrum performance, as well as in the verification of network coverage, network measurements, and network optimization. In the field of radio networks, its features include dual-band operation, real-time capabilities, handover optimization, receiver parameters optimization and alarm monitoring systems. It also offers great capabilities in the planning and installation of radio systems. This makes it one of the preferred tools for troubleshooting and monitoring radio networks in both laboratory and production environment.

Its primary application area is in the assessment of mobile phone systems. It supports a wide range of mobile phone technologies, such as GSM, CDMA and WCDMA, making it ideal for in-depth analysis and troubleshooting of any mobile phone system. It is used to measure signal level, signal quality, receiver performance, noise interference, and other such parameters to test the overall performance of the system. Moreover, its advanced statistical measurements capabilities help in the network optimization process. It also can assess the multipath propagation behavior of a given signal, which is essential for proper system optimization.

In addition, it is also used in the optimization of smart antenna arrays, which are required to provide the best coverage of a given wireless network. It can also be used to verify the performance and reliability of any new technology (such as WiMAX), and to evaluate their suitability for a particular environment.

Working Principle

At its core, the DS31412 consists of a main controller and several main control cards, with the main controller acting as the originator for all instructions. The main controller is responsible for receiving instructions from the user and sending them to the appropriate module. It also takes care of all the necessary configuration and maintenance of the device.

There are multiple modules in the spectrum analyzer which can be used to analyze a given signal. These include the frequency setting module, the power detection module, the envelope detector module, the modulation profile module and the spectrum window module. All these modules work together to analyze the signal according to the configuration given by the user. The main controller sends commands to the various modules and reads back their data, which can then be further processed.

The frequency setting module is used to specify the frequency range to be used for the analysis. The power detection module is responsible for measuring the power level at each frequency. The envelope detector module determines the amplitude of each frequency in the desired range. The modulation profile module then measures the modulation characteristics of the signal. Finally, the spectrum window module is responsible for displaying the amplitude of the carrier frequencies. After the analysis is complete, the results are then diagrammed for easy interpretation by the user.

In addition to its primary functions, the DS31412 can also be used to evaluate and optimize the physical properties of a given radio system. These include measurement of Group Delay, Proportional Delay and Doppler Spread. It also has a built-in alarm system, which can alert the user in a timely manner of any changes in the wireless system.

The DS31412 makes spectrum analysis easy, reliable and accurate. It cuts the time and cost involved in testing, analysis and troubleshooting of any radio network. Its wide array of features and capabilities make it a preferred choice for any quality assurance and optimization task.
