Abstract
This article describes the use of a low-cost softwaredefined radio applied to an Electromagnetic Compatibility (EMC) test. The proposed system is indicated for cases when an autonomous instrument is better suited, i.e., when there is no need for external signal or power connections. As a proof of concept, a metallic cavity has its shielding parameter measured, and the obtained results illustrate the kind of outputs the instrument can provide. Details concerning the hardware and software utilized are mentioned, alongside observed pitfalls and trade-offs. It is an affordable and versatile method, which can replace the traditional use of spectrum analyzers and receivers, especially in precompliance tasks.
