MWR-135UW- radio receiving measuring device

RFU with 17 "graphic touchscreen display for detailed signal examination. The new architecture of the RFU allows you to simultaneously obtain high selectivity (90 dB nom.), A wide maximum receive bandwidth (260 MHz), low spurious components (-90 dBc nom.) using direct digital frequency synthesis (DDS) and a modified PLL that downsizes the frequency with mixers instead of dividers. This provided a low level of phase noise (-139 dBc / Hz nominal at 10 kHz offset from the 1 GHz carrier), which allows receiving low-power signals near powerful interfering signals, as well as a high tuning rate. generation Kintex-7, has a built-in 2 GB DDR memory. The processing power of the DSP board provides the following capabilities: Real-time spectrum analysis in a 260 MHz bandwidth Minimum resolution bandwidth (RBW) of 0.1 Hz, which expands the capabilities of working with low-power and ultra-narrowband signals 10 Gb / s I / O interface (Ethernet SFP + ) for real-time transmission of time samples, complex or real spectra of signals with a bandwidth of up to 130 MHz to a storage device or processing system. The duration of the recording is limited by the volume of the external storage device. FPGA programming is available to the user. Optionally, the RPU is supplied in a coherent synchronous two-channel implementation. In this configuration, the local oscillator, the ADC clock frequency generator, and the measurement start signal are common to both receive channels. Those. 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
