Our standard warranty is for a 2-year time period. An extended warranty is available up to a total of five years (2-year warranty plus 3 additional years). Extended warranties are calculated at 6% of the product cost, per year.

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.

• Range: 100 kHz to 20.0 GHz
• RF Input Impedance (type-N connector): 50Ω
• Calibrated Streaming I/Q: 5 kHz to 40 MHz of selectable I/Q bandwidth
• Includes an internal GPS, used for timebase synchronization, I/Q timestamping, and GPS positioning
• Resolution Bandwidths (RBW): 0.1 Hz (≤200kHz span) to 3 MHz (any span) using 40 MHz IBW; 30 kHz to 10 MHz using 160 MHz IBW
• Timebase Accuracy: GPS disciplined OCXO remains within ±5 x 10-10 when locked to GPS;
– holdover of ±5 x 10-9 per day for aging;
– holdover of ±1 x 10-8 for temperature over -40°C to 60°C
