Rigol's DSA800 Series spectrum analyzers redefine the product category by setting new standards for performance and price. The DSA800 family features a widescreen display, compact design, and easy-to-use interface making it ideal for benchtop or field apps in RF and wireless testing and production. The spectrum analyzer offers the ability to measure smaller signals using our digital IF filter, which allows for smaller bandwidth settings and reduces displayed noise levels. The DSA815 distinguishes between signals with a frequency difference as little as 100 Hz. The DSA832 and DSA875 have RBW settable down to 10 Hz and a DANL (displayed average noise level) down to -161 dBm (typical). The DSA832E models provide additional value for applications without as stringent requirements. In addition, Rigol offers great options including an EMI filter and quasi-peak detector kit, VSWR measurement package, and tracking generator ("-TG" version) for all of these models. A Preamplifier is standard on the DSA815 and a great addition on the DSA832 or DSA875. Whether your application is radio verification at 455 MHz or monitoring the 3rd harmonic of 2.4 GHz signals find the right spectrum analyzer in the DSA800 Series.
