Wideband I/Q data recorder enables field-to-lab tests with midrange equipment

For the many worldwide users of a Rohde & Schwarz R&S FSV signal and spectrum analyser and an R&S SMBV100A or R&S SGT100A vector signal generator, field-to-lab test scenarios are now achievable with the R&S IQW100. Typical applications for the device are signals for cellular communication, EME, GNSS, or radio or TV broadcast.

Users can record signals obtained with the analyser in any selected environment, then replay the recorded signals utilising the generator. Signals acquired with the analyser are transferred to the device employing the standard digital I/Q interface available with selected company's equipment and stored as IQ data. To regenerate the recorded signal, the data is again transferred employing the same standard digital I/Q interface to the signal generator. Signals with a maximum bandwidth of 160MHz, with a sampling rate up to 200MS/s, are supported; ideal for all WLAN/WiFi signals, and all mobile standards in current commercial use.

Both the R&S IQW and R&S IQW100 are conventionally operated through LAN to input SCPI commands or utilising a web-based GUI that automatically adjusts to the current screen size. Alternatively, work locally either using the 5.7" TFT touchscreen or by connecting a keyboard and mouse.
