Description
Rigol DSA875 – 7.5 GHz Spectrum Analyzer
- 9 kHz to 7.5 GHz Frequency Range
- -80 to -98 dBc/Hz @10 kHz offset Phase Noise
- Total Amplitude Uncertainty from <1.5 dB to <0.8 dB nominal
- 100 or 10 Hz Minimum Resolution Bandwidth (RBW) available
- All-Digital IF Technology
IF Design Benefits
- The ability to measure smaller signals: on the basis of this technology, the IF filter enables smaller bandwidth settings, which greatly reduce the displayed average noise level.
- The ability to distinguish between small signals by frequency: using the IF filter with the smallest bandwidth setting, it is possible to make out signals with a frequency difference of only 10 Hz.
- High precision amplitude readings: this technology almost eliminates the errors generated by filter switching, reference level uncertainty, scale distortion, as well as errors produced in the process of switching between logarithmic and linear display of amplitude when using a traditional analog IF design.
- Higher reliability: compared with traditional analog designs, the digital IF greatly reduces the complexity of the hardware, the system instability caused by channel aging, and the temperature sensitivity that can contribute to parts failure.
- High measurement speed: the use of digital IF technology improves the bandwidth precision and selectivity of the filter, minimizing the scanning time and improving the speed of the measurement.
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. 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.
