What is an EMI Receiver?
A. An EMI Receiver is a tunable, sensitive voltmeter used to measure electric and magnetic field strengths. Most are similar to specialized spectrum analyzers, but are characterized by having preselectors, several detector functions, a housing shielding effectiveness of at least 90 dB and other unique additions. The frequency coverage of high-end receivers is typically 30 Hz to 22 GHz. Measurement bandwidths are variable to cover broadband and narrowband measurements.
