Electrical and magnetic disturbances are best identified using an EMC receiver/EMI analyzer with built in quasi peak detectors, noise floor extension and software features to identify electromagnetic events that can occur in speeds not managed well by most spectrum analyzers.
The EMC Shop specializes in radiated and conducted emissions testing. For CISPR or MIL complaint EMC receivers, or precompliance EMI spectrum analyzers, The EMC Shop stocks the right EMC analyzer for your testing needs. For precompliance testing, evaluation or troubleshooting, a standard spectrum analyzer doesn't always get the job done.
