For example, a receiver used for commercial compliance testing must comply with CISPR16-1-1, while a receiver used for military compliance testing must comply with MIL-STD-461. Other features, while optional, can be critical for making measurements or providing analytical capabilities essential for diagnostics. These analytical tools can be valuable in the isolation and identification of emissions problems. This application note will discuss what makes an EMI receiver fully compliant and provide an overview of some of the most useful internal diagnostic tools for quickly and efficiently analyzing and measuring unwanted emissions. Important features not required by CISPR 16-1-1 or MIL-STD-461 but that are critical for making measurements will also be discussed. CISPR 16-1-1 Compliance CISPR
