R&S®IQW Image

The R&S®IQW from Rohde & Schwarz is a Wideband I/Q Data Recorder which is used for fast and reliable real-time recording, storage, and playback of wideband I/Q data streams. In contrast to field tests, recording of live RF scenarios allows users to perform tests in the lab under real-world conditions reproducibly and at a lower cost. With the R&S®IQW, I/Q data with a bandwidth up to 512 MHz can be recorded, stored, and played back without any sample loss. This allows users to capture wideband live RF scenarios. Unlike artificially generated signals, users can employ the signals for lab tests relying on realistic scenarios. In combination with Rohde & Schwarz signal and spectrum analyzers and signal generators, the R&S®IQW can be used in a wide variety of situations for recording, archiving and playback of GNSS, communications and radar signals, as well as complex signal scenarios.

The innovative GUI of the R&S®IQW ensures easy handling of the recording and replay process. The device has a user-optimized and clean GUI that gives a structured overview of the device properties and functionalities. This system features a removable SSD memory pack that can be released by a lever mechanism. For users, this means fast data provision, allowing data to be exchanged easily and reliably between different users. In addition, memory expansion is possible by choosing a memory pack with a higher capacity. Different memory sizes are available for the R&S®IQW. The R&S®IQW-BD115 option contains a 15 Tbyte SSD memory pack and the R&S®IQW-BD106 option contains a 6.4 Tbyte SSD memory pack for recording bandwidths up to 512 MHz. The R&S®IQW-BD115 allows realtime recording up to 98 minutes. The R&S®IQW-BC103 option contains a 3.2 Tbyte SSD memory pack for recording bandwidths up to 200 MHz. With its very short boot time, the Linux based operating system ensures fast availability while reducing vulnerability to external malware attacks.

The R&S®IQW has a sturdy stainless steel case, and its 3 HU by ½19" format is very compact, measuring 9.80 × 5.90 × 17.76 inches, making it suitable for both stationary and mobile use. The wide recording bandwidth and high sampling rate and bit depth of the R&S®IQW make the instrument ideal for deployment in areas such as aerospace and defense, and for R&D of wideband communications systems.
