The DSA800 series of spectrum analyzers collectively covers the 9 kHz to 1.5, 3.2, or 7.5 GHz frequency range. These systems feature a widescreen display, a compact design, and a simplified interface, making it ideal for benchtop or field apps in RF and wireless testing and production. The analyzers employ a Rigol digital IF filter to allow for smaller bandwidth settings and a reduction in displayed noise levels.
The DSA815 distinguishes between signals with a frequency difference as little as 10 Hz. The DSA832, DSA832E, and DSA875 have a DANL (displayed average noise level) down to -161 dBm (typical). 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. Some of the benefits of using Rigol’s all-digital IF design include:
- The ability to measure smaller signals
- The ability to distinguish between small signals by frequency
- High precision amplitude readings
- Higher reliability than traditional analog designs
- High measurement speed
