Signal Hound SM200B 20GHz Spectrum Analyser



SM200B 20GHz Spectrum Analyser

The Signal Hound SM200B 20GHz Spectrum Analyser 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 (learn more about this feature).

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.

The Signal Hound SM200B 20GHz Spectrum Analyser is a high-performance 20GHz spectrum analyser and monitoring receiver, designed for fast and accurate data analysis at the lowest cost possible. The SM200B features:

  • Tunes from 100 kHz to 20 GHz
  • Sweeps at 1 THz/sec at 30 kHz RBW
  • 160 MHz of instantaneous bandwidth
  • 110 dB of dynamic range
  • Ultra-low phase noise
  • GPIO port antenna switching

It is important to note that all required software is included for the SM200B to operate. As with other Signal Hound devices, our Spike software provides the device controls, signal visualization display, and data export tools. Spike offers a variety of analysis modes and provides specific tools for EMC precompliance testing, interference hunting, and digital demodulation, amongst others.

For TSCM-specific applications, the SM200B 20GHz spectrum analyser is also compatible with the Kestrel software package for the ultimate in affordable and powerful countermeasure solutions.
