Signal Hound has developed the SM200A RF spectrum analyzer to rival the most expensive spectrum analyzers, yet priced to provide unrivaled value. Covering 100 kHz to 20 GHz, the SM200A offers 160 MHz instantaneous bandwidth for event triggering, 40 MHz calibrated streaming I/Q, 110 dB dynamic range, 1 THz/sec sustained sweep speeds (with the resolution bandwidth ≥ 30 kHz) and phase noise low enough to contribute less than 0.1 percent error to EVM measurements. The analyzer has a 20 MHz to 20 GHz preselector using a switched bank of 21 sub-octave filters, making it well-suited for signals intelligence, surveillance countermeasures, spectrum monitoring and applications with low amplitude signals in the presence of higher power signals.
To minimize weight and offer flexibility and economy of design and maintenance, the SM200A is “headless,” meaning the analyzer is connected to a laptop computer or a PC and display. Signal processing is distributed between a powerful onboard Arria-10 FPGA and the external PC with an Intel Core i7 processor. The Signal Hound SM200A can be used on the benchtop or, with its application programming interface (API), integrated in an automated monitoring or test system. The API allows customer access so the stream of I/Q data can be processed with custom DSP algorithms.
The SM200A sells for $11,900, including all the hardware to power the analyzer and connect it to a PC. Spike, Signal Hound’s powerful and free PC-based spectrum analyzer software, is also included. Spike provides SM200A controls, a signal visualization display and data export tools to help accurately analyze RF measurements, with various analysis modes, tools and utilities for phase noise testing, EMC pre-compliance testing, interference hunting and digital modulation measurements.
