SM200B — 20 GHz Real-time Spectrum Analyzer
The SM200B is a high-performance 20 GHz spectrum analyzer and monitoring receiver with 110 dB of dynamic range and 1THz/sec sweep speeds. The SM200B offers 160 MHz instantaneous bandwidth (IBW) calibrated I/Q capture, available through block transfer of a 2-second I/Q buffer over USB 3.0 to the PC.
The SM200B is a high-performance spectrum analyzer and monitoring receiver. Tuning from 100 kHz to 20GHz, the analyzer has 160 MHz of instantaneous bandwidth (IBW), 110 dB of dynamic range, 1THz/sec sweep speed at 30kHz RBW (using Nuttall windowing), and phase noise performance that is low enough to contribute less than 0.1% error to EVM measurements and rival even the most expensive spectrum analyzers on the market.
The SM200B offers 160 MHz instantaneous bandwidth (IBW) calibrated I/Q capture, available through block transfer of a 2-second I/Q buffer over USB 3.0 to the PC.
Signal processing is distributed between a very powerful Altera FPGA and an external PC having an Intel Core i5 processor. The Signal Hound SM200B can be readily interfaced, using its local API, to an automated monitoring system or to automated test equipment. The SM200B API provides customers the access needed to insert their own DSP algorithms into a calibrated stream of I/Q data.
