IQR I/Q Data Recorder

Rohde & Schwarz has been continuously enhancing its R&S IQR100 digital I/Q data recorder. A new firmware update now provides users with a data rate of nearly 100 Msample/s instead of the original 66 Msample/s. Plus, the exchangeable memory pack's capacity has been increased from 1 Tbyte to 2 Tbyte.

The R&S IQR100 digital I/Q data recorder from Rohde & Schwarz can now record, store and play I/Q signals with bandwidths up to 79.6 MHz -- loss-free in realtime. Even parallel recording of position data and automatic gain control (AGC) reference levels is possible. The AGC function allows a wider dynamic range without the danger of overload.

Used in combination with test instruments from Rohde & Schwarz, the R&S IQR100 can be used for the mobile capture of RF spectra such as GNSS, wireless communications and broadcast signals, and in research and development for providing interference and test signals. Depending on the required bandwidth, an R&S FSW or R&S FSV signal and spectrum analyzer or an R&S TSMW drive test scanner serves as RF frontend for providing the I/Q data via the R&S Digital I/Q Interface. The recorded I/Q data can be output in realtime to an R&S SMBV signal generator at a later point in time. This makes it possible to generate a realistic signal spectrum for testing DUTs equipped with an RF interface. Alternatively, the I/Q data can be exported to a PC via LAN or a USB storage device for data storage and further processing, or for spectrum analysis.

Rohde & Schwarz is showcasing the R&S IQR100 I/Q data recorder at electronica (hall A1, booth 307). The instrument is now available from Rohde & Schwarz.
