Engineers integrating WiFi, Bluetooth and other modern RF technologies are confronted with complex challenges like frequency hopping signals, channel conflict, and spectrum interference. Real- Time Spectrum Analyzers bring the dimension of time to RF Analysis making it easier to monitor and characterize these complex RF systems. Recently Rigol Technologies has released two new series of spectrum analyzers, RSA5000 (the end of 2017) and RSA3000 (2018), which combine industry leading real-time performance (7.45 μs 100% POI), rich data displays, and advanced triggering options allowing the user to quickly capture, identify and analyze these complex events.

This autumn was the most important season for Rigol Technologies Inc. because on October 18, 2018 the company celebrated its 20th anniversary! Over 200 guests from around the globe including special guests and partners gathered to participate in the grand event. China News Service, People’s Net, China Net, and other central media reporters as well as a number of industry media reporters were invited to attend the celebration. Rigol also received greetings and wishes from hundreds of customers and partners from different countries around the world including Europe, the United States, Japan, Russia and so on.

Development of telecommunication technologies, new standards of wireless data transmission and their continuous improvement require new devices use to analyze radio- frequency spectrum since ordinary swepttype spectrum analyzers are no longer suitable to solve the whole complex of tasks. Signals become increasingly complicated with jumps from one frequency to another, electromagnetic environment keeps on deteriorating, and the possibility of signal omission or its incorrect analysis is very high. In this case the best solution would be to use a real-time spectrum analyzer.
Rigol Technologies, Inc. announced a new series of real-time spectrum analyzers RSA3000. The new series includes 4 models: with maximum 3.0 GHz frequency (RSA3030 and RSA3030-TG) and 4.5 GHz (RSA3045 and RSA3045- TG). Similar to RSA5000 the new series uses innovative UltraReal technology which allows real-time capture of signals with 9.3 μs minimum duration (7.45 μs as an option) in up to 10 MHz band (40 MHz as an option).

In previous issues of our magazine we published the articles dedicated to various test and measuring devices produced by RIGOL Technologies, Inc. We provided full and detailed information about such equipment like spectrum analyzers, digital oscilloscopes, signal generators, programmable power supplies. This time the present article will cover programmable electronic loads. This is the main innovative product of 2017 for the company and in general electronic loads production is the new trend for RIGOL. New RIGOL electronic loads series introduced in Spring 2017 got DL3000 model index and it contains four DC models: DL3021, DL3021A, DL3031 and DL3031A. Maximum input voltage for all models is 150 V and input current — 40 A (DL3021, DL3021A) or 60 A (DL3031, DL3031A). Find more details in the present article.

In 2015 in December issue of KIPiS magazine we published article «Up-todate Rigol spectrum analyzers». At that moment RIGOL Technologies, Inc. had three basic models: DSA815 (with 9 kHz…1.5 GHz frequency range), DSA832 (up to 3.2 GHz) and DSA875 (up to 7.5 GHz). But everything tends to change with time and the family of Rigol spectrum analyzers has also changed and replenished with new models following from high-end devices to low-end ones. Thus basing on DSA832 Rigol produced DSA832E and basing on DSA815 the company produced DSA700 series of two models — DSA710 and DSA705. As exception DSA875 doesn’t have any low-end model basing on it. Find more details about all of the above Rigol models and their functional capabilities.
