Rigol real time spectrum analyzers with vector network analysis from Saelig

30 July 2020

The Rigol RSA3000 and RSA5000 real time spectrum analyzer series available from Saelig Company Inc. now includes five “N” versions that offer vector network analysis up to 6.5 GHz. Built on the Rigol Ultra Real platform, these vector network analyzers (VNAs) offer S11 and S21 reflection and transmission analysis and feature multi-touch user control via a 10.1 in LCD touchscreen. Front panel buttons, keyboard and mouse input are also available for a straightforward user interface. They run on a Linux operating system to provide a reliable and stable interface, with remote communication access also available.

Users needing to characterize active or passive components, identify signal path errors or tune antennas will benefit from this VNA solution, which enables complex measurements including distance to fault and S parameters. S11, or forward reflection co-efficient, allows engineers to quickly visualize and measure a component’s response on a Smith chart and polar plane while measuring the component’s magnitude and Source: Saelig Company Inc.Source: Saelig Company Inc.standing wave ratio, which are important when characterizing the performance of passive components such as attenuators, splitters and filters.

S21, or forward transmission coefficient, allows engineers to quickly visualize how amplifiers, filters and cabling components affect impedance or phase as a function of frequency. View phase or group delay as a function of frequency or magnitude to quickly determine and confirm critical specifications. Distance to fault measurements allow engineers to easily debug connectivity issues that cannot be seen from visual inspection. The spectrum analyzer uses signal reflections to calculate the distance to a fault anomaly. It is useful for debugging communications system and completing cable test as well as for optimizing performance and throughput of a network.

The analyzer series measurement possibilities include EMI, RTSA, VSA and VNA modes in addition to the traditional GPSA mode. Engineers may find it convenient to address multiple RF test challenges with just one instrument, effectively reducing their time and costs and greatly improving their working efficiency. Advanced measurement mode provides settings required for transmitter testing such as multichannel power, ACP and occupied bandwidth. Quickly recall the limit line compliance with the CISPR standard (EN55011, EN55012) to carry out pre-test and monitor the target point with three different detectors.
