Firmware update boosts data recorder sample speed
A new firmware update has been added to Rohde & Schwarz’s R&S IQR100 digital I/Q data recorder. It 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 data recorder 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 other 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 analyser 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.
