National Instruments China Corp. (NI China) has partnered with Chengdu Huari Telecommunication Co. (Huari Telecom), a developer and manufacturer of radio directional finding systems in China.

Huari Telecom and NI China local system integrator VI service network developed the HR-100, a patent-pending wideband radio receiver and monitoring system based on the National Instruments PXI-5660 RF vector signal analyzer.

With the new system, users are able to enhance functions for monitoring signals inside and outside government-regulated frequency bands while pinpointing the source of transmission or interference with the signal identification and directional finding capabilities.

The HR-100 system also provides multiple RF parametric functions, such as constellation analysis and time-frequency analysis. The system is claimed to pass the validation test of the China Radio Administration Bureau, an authoritative governmental institute for radio management.

Huari Telecom will use the system as both a radio receiver and an RF vector signal analyzer to monitor modern wideband digital telecommunication signals and conventional narrowband analog broadcast signals. In addition, Huari Telecom engineers will be able to configure the system as a single-channel receiver or a multiple-channel directional finding system. They leverage the 20MHz IF bandwidth of the NI PXI-5660 RF vector signal analyzer for innovative simultaneous multiple signal direction finding.

The software includes a radio receiver toolset based on National Instruments LabVIEW software with a C interface developed by VI Service Network. The system is comprised of the National Instruments PXI-5660 RF vector signal analyzer, the NI PXI-8187 2.5GHz Pentium 4 embedded PXI controller and the PXI-1042 eight-slot PXI chassis, in addition to accessories and services from Huari Telecom and VI Service Network.
