New high-end wideband I/Q data recorder allows realistic device tests in the lab

The Rohde & Schwarz R&S IQW wideband I/Q data recorder can be used to record signal scenarios typically needed in test cases at a bandwidth up to 512MHz and high sampling rates. The device records wideband RF signals and reproduces them to reproduce real-world test environments, allowing realistic, repeatable device tests in the lab. The solution comprises of an R&S FSW signal and spectrum analyser, the new IQW wideband I/Q data recorder and an SMW200A vector signal generator from the company. The IQW records the signal spectrum of a wideband RF signal or the spectra of various narrowband signals in a frequency band, with a bandwidth up to 512MHz. This makes it perfect for realistic component tests with radar signals, for deployments using a variety of RF test scenarios in the automotive sector, and for tests using GNSS signals, for example. Signals are captured by an R&S FSW signal and spectrum analyser. The instrument acquires signals with high sensitivity, generates the corresponding I/Q data in real time and transfers the data gapless to the IQW. The FSW comes in seven models for frequency ranges up to 90 GHz. The wideband I/Q data recorder is normally operated via LAN using a web-based GUI that automatically adjusts to the actual screen size. The recorder can also be run locally via its 5.7" TFT touchscreen, with the option of attaching an accessory keyboard and mouse.
