IQR digital I/Q data recorder

Rohde & Schwarz has introduced the R&S IQR digital I/Q data recorder, designed to record, store and replay digital rf signals loss free and in real time over the I/Q interface.

When used in combination with rf scanners, generators and network analysers, the recorder is said to complete a high performance, continuous analysis system for digital rf signals. The system is aimed to be of particular benefit for users in broadcasting, mobile radio, aerospace, defence, and the automobile industry. According to the company, the recorder offers transmission rates of up to 66Msample per second. The device, in half 19in format, is said to come with a robust, interchangeable solid state drive with one Tbyte of storage capacity and a recording rate of 270Mbyte per second. The company claims it is ideal for use in drive tests in broadcasting and mobile radio networks. For instrument tests or electronic component testing, the recorder has been designed to supply previously generated test signals. Broadband spectra or sporadic signals can reportedly be recorded in real time for later offline analysis. The integrated Ethernet interface is said to permit remote control of the instrument as well as the transfer of the measurement data via LAN. Extra features are said to include two additional USB interfaces on the front panel and a touch screen.
