The IQFR1-RU from LitePoint is a 5G FR1 O-RAN Radio Unit Test System that operates from 600 to 6000 MHz. This test system supports 3GPP 5G NR RF downlink and uplink measurements, as well as the O-RAN C/U/M/S-plane functionality, necessary for configuring the interface between the test equipment and the O-RU under test. It has a compact 2U architecture, encompassing multiple independent Vector Signal Generators (VSGs) and Vector Signal Analyzers (VSAs) for 5G sub-6GHz waveform generation and analysis. The VSGs generate an output power of 0 dBm to -120 dBm (less than 5000 MHz) and -5 dBm to -120 dBm (more than 5000 MHz). These VSAs can handle a peak RF input power of +36 dBm, have an input return loss of over 8 dB and a noise figure of less than 25 dB.
The IQFR1-RU is designed to validate RF parametric measurements and functional performance of the DUT over its split 7.2x interface. It has integrated RF signal generation, analysis, RF front-end routing hardware, and optical links. This test system supports up to eight bi-directional RF ports, which are fully calibrated to provide maximum flexibility and significant time savings during setup. It eliminates dependency on the DU emulator and external switch/combiner, allowing easy scalability from lab to production. It supports S-plane time synchronization using the IEEE1588 Precision Time Protocol (PTP) over the O-RAN interface.
The IQFR1-RU requires an AC supply of 100-240 V and consumes less than 550 W of power. It can be controlled via USB 3.0 and 1000 Base-T LAN RJ-45 interfaces. This test system is available in a benchtop module that measures 381 x 91.5 x 541 mm and has N-Type female & BNC connectors.
