Rigol DSA800 Series Spectrum Analysers

Rigol has added the DSA832 and DSA875 models to its DSA800 series of spectrum analysers, which offer a bandwidth range from 9 kHz–32 GHz (DSA832) and 9 kHz–7.5 GHz (DSA875).

The series features a widescreen display, compact design and simple-to-use interface and operations, making it suitable for benchtop or field apps in RF and wireless testing and production. Using Rigol’s digital IF filter technology, the series can measure smaller signals. The device enables users to distinguish between small signals by frequency on the smallest bandwidth setting, making it possible to discern signals with a frequency difference of only 10 Hz.

The technology almost eliminates the errors generated by filter switching, reference level uncertainty and 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. Compared to these designs, the digital IF reduces the complexity of the hardware, the system instability caused by channel ageing and the temperature sensitivity that can contribute to parts failure.

Using digital IF technology also improves the bandwidth precision and selectivity of the filter in the devices, thereby minimising the scanning time and improving the speed of measurements. The models also feature RBW that is settable down to 10 Hz and a DANL (displayed average noise level) down to -161 dBm (typical). An EMI filter, quasi-peak detector kit and tracking generator are also available for these models.
