MWR-135U – radio receiving measuring device

Measuring receiver MWR-135U is used to measure radio signals in the frequency range from 200 Hz to 13.5 GHz. There are models depending on the frequency range: 4 GHz, 8.5 GHz, 10 GHz, 13.5 GHz. Features of MWR-135U digital signal processing based on the latest generation FPGA Kintex-7 with built-in 2 GB DDR memory. The processing power of the DSP board provides flexibility in measuring receiver configuration and automated measurement algorithms. The receiver oscillator is based on direct digital frequency synthesis (DSS) and a modified PLL that downsizes the frequency with mixers instead of dividers. Thus, a low level of phase noise (-139 dBc / Hz nominal at an offset of 10 kHz from a 1 GHz carrier) has been achieved, which makes it possible to receive low-power signals near powerful interfering signals, as well as an acceptable tuning speed. synchronous monitoring of coherent channels, it is enough to optionally add one more channel. In this case, structurally, it is a circuit in which the local oscillator, ADC clock generator and trigger are common to both receive channels. Application of MWR-135U: signal spectrum analysis in the frequency range up to 13.5 GHz in real time with capture up to 260 MHz for analyzing broadband signals Measurement of various types of modulation Measurement of radio interference and useful signals Accurate measurement of frequencies Advantages of the MWR-135U model: production in Russia: delivery, calibration, verification and service do not depend on sanctions Possibility to work in the microwave range, up to 13.5 GHz High selectivity (90 dB nom.) Wide maximum receive bandwidth (260 MHz) Low spurious level (-90 dBc nom.) FPGA user programmability Transfer of time samples to a computer at up to 10 Gb / s (Ethernet SFP +) for spectrum storage or processing in real time. control of measurements and control of the device is carried out using the built-in the device can be mounted in a 19 '' rack to create a multi-device measuring complex thanks to the removable carrying handles based on the hardware and software complex Analysis of the operational characteristics of radio communication networks Radio monitoring and radio direction finding / Tech. specifications Operating frequency range: 200 Hz – 4 GHz, 8.5 GHz, 10 GHz, 13.5 GHz (options) Sensitivity at 25 ° C: -166 dBm / Hz (-164 dBm / Hz) Selectivity: 90 dB Dynamic range: 153 dB (148 dB) Number of antenna switch channels: 2
