A 10GbE-connected spectrum analyzer unrivaled in value

The SM200C is a high-performance spectrum analyzer and monitoring receiver with a 10 Gigabit Ethernet SFP+ port, enabling the SM200C to communicate with a PC over long distances using a fiber optic cable. Designed for remotely-located accurate RF data analysis at the lowest cost possible, the SM200C features:

  • 160 MHz instantaneous bandwidth I/Q streaming over 10GbE
  • SFP+ port for fast, long-distance communication with a PC using an optic cable
  • Device control and data transfer occurs via SFP+ connection, not USB
  • Tunes from 100 kHz to 20 GHz
  • Sweeps at 1 THz/sec at 30 kHz RBW
  • 110 dB of dynamic range
  • Ultra-low phase noise
  • GPIO port antenna switching
