Rigol DSA-815-TG Spectrum Analyzer 1.5 GHz Rigol's new DSA-815-TG spectrum analyzer redefines the product category by setting new standards for performance and price. The Rigol DSA-815-TG features a unique widescreen display, compact/lightweight design, and easy to use interface and controls, making it ideal for benchtop or field use in RF and wireless testing and production. This new spectrum analyzer offers the ability to measure weaker signals using Rigol's digital IF filter, which allows for smaller resolution bandwidth settings, reducing displayed noise (DANL or Noise Floor) levels. The DSA-815-TG has the capability to distinguish between signals with a frequency difference of as little as 100 Hz. The DSA-815-TG includes a wide range of standard functions including AM/FM demodulation and a built-in RF preamplifier. In addition, Rigol offers great options including an EMI filter and Quasi-Peak detector, a 1.5 GHz Tracking generator (included in the DSA-815-TG), and VSWR measurements. The Rigol DSA815-TG is a compact and light Spectrum Analyzer with premium performance for portable applications. The use of digital IF (intermediate frequency) technology guarantees reliability and performance to meet the most demanding RF applications. The very large display (20.3 cm / 8") of the Rigol DSA815 Spectrum Analyzer with a resolution of 800x480pixels provides a very good overview over all its comfortable functions like Auto Tune, Auto Range, Auto Scale and Auto Couple. These functions enable the analyzer to acquire signals and match parameters automatically, eliminating the manual process necessary with a traditional analyzer. Rigol Spectrum Analyzers have a sophisticated yet easy to use user interface and offer multiple functions for all tasks. The menu navigation is very intuitive and all functions and parameters are easy to reach because of the graphical interface.
