The R&S FS300 is a spectrum analyzer covering a frequency range of 9 kHz to 3 GHz. Using a modern, digital frequency processing technique, it delivers high measurement quality at a favourable price. It is built as a versatile instrument for comprehensive measurements on the lab bench, in service, and as a flexible measuring instrument in automatic production systems.
The instrument addresses several measurement applications: measurement of RF spectrum (level and frequency), measurement of radiated interference (EMC), time-domain measurement, and radiomonitoring remote-controlled via USB. Operation is menu-guided with clear menu structures, so that even untrained users can quickly obtain correct results, while users already familiar with Rohde & Schwarz spectrum analyzers will recognize the menu items from other Rohde & Schwarz instruments.
ValueTronics keeps its inventory under its own roof, holding and stocking equipment in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units are shipped factory-sealed exactly as received from the manufacturer.
