1 Overview
This document outlines the operation and functionality of the SM200A/B/C and SM435B Signal
Hound spectrum monitor and spectrum analyzer. This document will help you understand the
capabilities, performance specifications, and features of your SM200 / SM435.
The SM200/435 is a real-time, high-speed, high dynamic range, low phase noise spectrum
analyzer and spectrum monitor, which communicates with your PC over a high speed data link.
It has 160 MHz real-time spectrum analysis bandwidth, 40 MHz (USB models) or 160 MHz
(10GbE models) real-time streaming I/Q bandwidth, tunes from 100 kHz to 20 GHz, and sweeps
1 THz/s at 30 kHz RBW, internally digitizing and processing 1 billion analog samples per second.
The SM435B has the same features as the SM200B, including the THz/s sweep speed, with the
caveat that some spans above 24 GHz may sweep slower than 1 THz/s.
The SM200A can stream up to 40MHz of I/Q bandwidth over USB 3.0.
The SM200B includes 2 GB of internal DDR memory, providing up to 2 seconds of 160 MHz BW
segmented I/Q capture read over USB 3.0.
The SM200C uses a 10 GbE SFP+ interface, and can stream up to 160 MHz I/Q bandwidth.
