IZT RecPlayApplicationsThe RF recorder is suitable for recording typicalreceive scenarios in different countries with excellentsignal quality. The recordings can be storedin a library for functional testing of receivers. Itis possible to record and replay signals of up toeight antennas.The recorder covers the frequency range from9 kHz to 3 GHz (optional 6 GHz / 18 GHz) witha realtime bandwidth selectable up to 25 MHz,which is sufficient to cover the whole FM broadcastband simultaneously. The replay generatorcovers the frequency range from 9 kHz to 3 GHzwith a bandwidth of 120 MHz, which allows tocombine different recorded and calculated scenariosinside this bandwidth.The IZT RecPlay System consists of three components:a recording system, a server with softwarefor off-line editing and signal sources to replaythe signals.Benefits include greatly reduced costs for fieldtesting, repeatable tests in the lab and fidelity inreproducing real RF environment which allows ashorter time to market.The record and replay system IZT RecPlay is theideal platform for RF receiver design validationof analog and digital radio, video and GlobalNavigation Satellite Systems (GNNS) anddevelopment of automotive car infotainmentsystems and chipsets.RecPlay SystemThe IZT RecPlay record and replay systemconsists of at least one IZT R3301 RF Recorderwith integrated high performance RF receiverand built-in server, an external server for datastreaming and one IZT S1000 signal generator forreplay of the recorded I/Q data (figure 1).An IZT RecPlay system for diversity recordingconsists of one IZT R3301 RF Recorder perRF RECORDER IZT R3301DIVERSITYRECORDINGRF RECORDER IZT R3301HHDorLANSYNC UNITIZT R3301-SNCHHDorLANSERVERIZT P1000Datastorage&off-lineprocessing&streamingantenna and is synchronized by an external clockdistribution (figure 2).A common reference clock alone (f.e. 10 MHz)will not be sufficient to ensure all receivers operatephase synchronous. Therefore, one master IZTR3301 creates all necessary clock signals, like systemclock and both VHF-UHF local oscillators, andsends them to a central clock distribution, whichamplifies the signals and passes them on to allreceivers. An additional trigger impulse starts thesample-synchronous recording of the system. Intercommunicationbetween master and slaves ofthe built-in servers is controlled via optical LANinterface to minimize EMI. The built-in GPS receiverof the master serves as time and locationreference.If necessary, a calibration signal can be coupledinto the antenna feeds, which allows to establishzero phase shift between the antenna inputs.The captured data streams of up to approximately120 MByte/sec are sent via internal GigabitEthernet to each built in server and is stored onan integrated RAID system.Figure 3 shows the block diagram of the recordingsystem configured for two diversity signals.The system is modular and can be expanded upto eight antenna signals.LANSIGNAL GENERATORIZT S1000DIVERSITY REPLAYINTERNETfigure 3: IZT RecPlay diversity setup with streaming server for data post processing2 | 3

Recording Systemfigure 4: FM broadcast recording with high dynamic rangeIZT R3301The IZT R3301 RF Recorder is a portable receiverwith built-in server for data recording. It is optimizedfor recording RF signals in mobile and portableapplications.The outstanding RF performance and signal processingmatches the professional IZT R3000receiver series. These receivers were developed forapplications of regulatory agencies, military andcivilian radio surveillance and as lab test equipment.They are designed to produce good signal qualityunder extreme dynamic range and have sucessfullypassed many rigorous technical evaluations withcivilian and military customers.With its very high dynamic range (figure 4) andexcellent phase noise this receiver platform is theideal solution for the needs of modern digitalmodulation standards.Thanks to its front panel control, touch screenand integrated processing hardware, the IZTR3301 RF Recorder is the perfect portable RFrecording system. While having a compact andrugged design, it also meets CISPR 25 / EN 55025for extremely low RF emissions. The wide rangeAC and DC power supply is completed by anuninterrupted power supply (UPS) for surge & subvoltage protection against DC supply fluctuations.An internal GPS module adds location informationto the received signals.The IZT R3301 is characterized as follows:• Portable, rugged design: 45 x 35 x 24 cm,approx. 17 kg• Continuous I/Q data recording with up to30 MSamples/s• Swappable RAID system (figure 5) for about11 hours of continuous recording with24 MSamples/s in 4 TB configuration• Built-in GPS for embedded location information• 10 to 30V DC power supply, approx. 125 W

IZT RecPlay• 100 to 240V AC supply with built-in UPS• Control via touch screen• Synchronization interface for diversity andmulti-frequency recording (figure 7)• Low RF emissions, meets EN 55025 / CISPR 25• Built-in high-end IZT R3000 receiver technologyThe outstanding RF performance of the integratedIZT R3000 receiver technology is based on a verymodern and market proven receive system withexcellent reception at very good signal quality.It is highly insensitive to strong adjacent bandinterference due to sub-octave preselector filtersand high first intermediate frequency.The integrated IZT R3000 receiver is characterizedas follows:• 9 kHz to 3 GHz frequency range• Frequency range upgradeable up to 18 GHz• Real-time bandwidth up to 25 MHz• Very low phase noise• High linear RF frontend for excellent IP3performance• Preselector filter-bank guaranties best IP2performance• Additional digital filtering• IF Filter bandwidth: 6.25 kHz to 25 MHz• 1 Hz tuning resolution• Multichannel recording of up to 4 differentbandwidths simultaneouslyAn external synchronization unit (figure 6) providesphase coherent clock to multiple IZT R3301RF recorders in diversity or multi-frequency setups.It can be enhanced by a calibrated signal source(connected directly to the junction plane of the antennaconnectors) in test scenarios where absolutephase difference between the antennas is needed(figure 3).Remote connection between multiple recorderunits is made via optical LAN interface to preventelectromagnetic interference. An optical LANconverter allows for complete remote control of asingle IZT R3301 unit over longer distances withoutEMI problems, for example in a highly sensitive RFmeasurement setup inside an EMI chamber.figure 5: Easy RAID storage swappingfigure 7: External interfaces for power supply, LAN, GPS antenna and synchronizationApplication Example 1:Diversity antenna setupThe system is ideal for handling phase coherentand frame synchronous recordings with multipleantennas at the same center frequency, e.g. forvalidation of FM broadcast diversity-tuners.This challenging use case requires a very highaccuracy in signal and data processing of therecord and replay system.Application Example 2:Multi-frequency antenna setupThe system also fits perfectly into handling framesynchronous recording with multiple antennachannels at different center frequencies. This is animportant use case for automotive customers fortesting seamless DAB to FM linking in the field.The setup allows also to record DAB and DVB orthe GPS satellite signal and any other service atthe same time.Of course application example 1 and 2 can be combinedfor covering both a phase coherent FMbroadcast diversity and also frame synchronous DABrecording by using a IZT RecPlay setup consisting ofthree synchronized RF recorders IZT R3301.figure 6: Synchronization unit IZT R3301-SNC4 | 5
