Test & Measurement R&S®IQR I/Q Data Recorder Realtime recording and streaming of digital I/Q data

R&S®IQR I/Q Data Recorder At a glance The R&S®IQR is a high-speed recorder for recording and playing digital I/Q data streams. When used in combination with one of the many Rohde & Schwarz instruments that have the R&S®Digital I/Q Interface, the R&S®IQR can store and play data in realtime. The R&S®IQR I/Q data recorder is an ideal storage medium for I/Q data streams. It can be used, for example, for providing interference or test signals, for drive tests, for realtime storage of data when archiving RF signals, and for playing recorded I/Q signals. The I/Q data recorder is well suited for research...

Fast storage and playing of digital I/Q data in realtime R&S®Digital I/Q Interface Many Rohde & Schwarz instruments have a digital I/Q inter­ face. The combination of different measuring instruments via the digital I/Q interface makes it possible to implement a wide variety of applications, from simple data recordings to providing complex RF test signals. The Rohde & Schwarz instruments compatible with the R&S®IQR are listed in the data sheet (PD 5214.4394.22). Digital I/Q data has real and imaginary parts, allowing the RF signal to be fully described. Key parameters are the sample rate and the...

Rugged, compact I/Q data recorder with removable memory pack Rugged, compact, 3 HU, ½ 19" format The very compact R&S®IQR I/Q data recorder has only 3 HU and a ½ 19" width, so it can be integrated in a 19" rack with other similarly compact instruments, such as the R&S®TSMW universal radio network analyzer or the R&S®SFE broadcast tester. The design of the housing, such as the stainless steel frame, and the use of SSDs as the system memory make the R&S®IQR suitable for operation under extreme conditions as occur during drive tests, for example. The data memory packs are simple to remove and insert,...

information directly Easy manual operation directly on the instrument In addition to a main settings menu, the instrument has a parameterization menu for recording and playing. The following functions can be parameterized: i Trigger definition (trigger source, trigger type) i Selection of file to be played or definition of file name i Record and play parameters Additional information such as the progress bar, sample rate, l/Q level, reference level and the names of the con- nected instruments is displayed to keep the user informed of the status before and during recording and playing. Graphical...

Numerous i ­nterfaces for data ­communications and control Ethernet interfaces for communications and data exchange The two Ethernet interfaces are used for communications between the R&S®IQR and connected instruments. This includes external control of the R&S®IQR using remote desktop and SCPI commands and the ability to control connected instruments that do not have a built-in monitor, such as the R&S®TSMW or generators. In addition, I/Q data can be exported and imported via LAN. BNC sockets for trigger and synchronization signals Except for two USB interfaces on the front panel, all electrical...

Export Configuration Source File... Dest. File... Export/Archiving Format Remaining Time Transfer Ftate Export Running Backup of recorded l/Q data files l/Q data recorded in realtime can be archived offline on cost-effective mass memories via the Ethernet and Export and import of l/Q data The R&S®IQR-K101 option allows an R&S®IQR l/Q data file in binary file format to be output to an external USB storage device such as a USB hard disk drive. The file can also be output via Ethernet for storage on an external network drive. This option also makes it possible to import individual l/Q data files....

trigger concept The extensive trigger menu provides many control options to start and stop recording and playing. Depending on the trigger source, the following modes are available: Triggering on the l/Q level prevents recording of nonrelevant data Triggering on the l/Q level optimizes the start of recording, providing a type of observation mode. In conjunction with a predefined recording time (record duration), the storage requirements can be limited to the data of interest. Triggering by external signals The rising or falling slope of external signals at a user- definable BNC socket can be...

Simultaneous recording and playing of several spectra Multiplexing and parallel output of I/Q data streams The R&S®IQR­K105 option supports the recording and playing of multiplexed I/Q data streams of the R&S®TSMW universal radio network analyzer. As a result, up to two spectra can be transferred simultaneously via the digital I/Q interface. The simultaneously stored spectra can be transferred to a PC for further processing (R&S®IQR­K101 option) or output to two generators equipped with the R&S®Digital I/Q Interface (R&S®IQR­K107 option). Simultaneous recording and playing of multiple spectra...

Continuous recording of position data and reference levels Recording and graphical display of position data eliminates need for video recordings Recording of GPS coordinates The ability to assign a location to the recorded spectrum is an important function for drive test applications. The R&S®IQR­K102 option allows GPS data to be trans­ ferred via USB from the R&S®TSMW GPS receiver or from the separate R&S®TSMX­PPS2 GPS receiver (see “Applications”). The time-synchronized GPS data is saved in a separate file together with the sample count, providing a clear allocation to the I/Q data stream....
