Digital I/Q data recorder from Rohde & Schwarz stores 1 Tbyte data for analysis of RF signals

Rohde & Schwarz introduced the R&S IQR digital I/Q data recorder to record, store and replay digital RF signals loss-free and in realtime over the I/Q interface. I/Q interface simplifies both parameter exchange between the instruments and the setup of the data recorder. Suggested for use in broadcasting, mobile radio, aerospace & defense, and the automobile industry. This recorder offers transmission rates of up to 66 Msample per second. It features solid-state drive with one Tbyte of storage capacity and a recording rate of 270 Mbyte per second.

The R&S IQR I/Q data recorder records digital RF signals in realtime. During configuration, the user can access several trigger modes for the start/stop function that range from manual quick start to the triggering of recording via a previously entered I/Q signal level. The integrated Ethernet interface permits remote control of the instrument as well as the transfer of the measurement data via LAN. Features two extra USB interfaces on the front panel and a touch screen.

The compact R&S IQR in half 19-inch format has three height units and is available in two models: The R&S IQR20 offers one I/Q input and output each for a maximum of 20 Msample per second. This economy model is intended for stationary operation with hard disk memory. The associated memory pack consists of a hard disk with 1 Tbyte storage capacity and a maximum data throughput of 80 Mbyte/s. The high-performance R&S IQR100 model features an I/Q input and an I/Q output capable of handling up to 100 Msample per second. It can be equipped with a robust 1 Tbyte solid-state drive with a maximum data throughput of 270 Mbyte/s. This configuration currently supports a data rate of 66 Msample per second.
