Anritsu S820C Overview

The Anritsu S820C spectrum analyzer is a wide band, very sensitive receiver. It works on the principle of "super-heterodyne receiver" to convert higher frequencies (normally ranging up to several 10s of GHz) to measurable quantities. The received frequency spectrum is slowly swept through a range of pre-selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of the Anritsu S820C. The CRT displays received signal strength (y-axis) against frequency ( x-axis). Some applications for Anritsu S820C Spectrum Analyzers include Site Monitoring: Verify that the frequency and signal strength of your transmitter is accurate. Interference: Before a system is installed you use a Anritsu S820C spectrum analyzer to verify that the frequencies (you plan to use) are not occupied or if the presence of a very strong signal will interfere with your new setup. Interference can be created by a number of different situations. Other tests that utilize the Anritsu S820C spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components. Microwave Site Master S810C and S820C utilizes vector error correction solving the most common and the most difficult accuracy problems of field test equipment operation and thus, improves system quality and reduces maintenance expenses. Difficult test specifications are easy to verify. Vector error correction and a simple, friendly user interface within the S810C and S820C further improves the quality and convenience of measurements compared to traditional scalar techniques. Vector error correction also improves the quality of Distance-To-Fault data. Not only is the reflection magnitude more accurate, the waveguide dispersion correction for fault distance (different frequencies travel at different speeds) is also more accurate and repeatable.
