Commercial and industrial conducted emissions are performed to verify potentical harmful leakage between 150kHz and 30 MHz. Aerospace and miltary standards extend the frequnecy requirements to 9 kHz and up to 400 MHz in some cases. For sophisticated designs a dedicated EMI/EMC analyzer or a high end spectrum analyzer to identify low noise issues. Standard low cost spectrum analyzers can be used for simple verficiation checks.

Most any signal or spectral analysis unit can be used to evaluate the quality of your electrical components and DUT's. Quasi peak detection and EMI filters are offered as options by many manufacturers. EMI Receviers and EMC analyzers have the required hardware and software to help identiry problem areas in both conducted and radiated applications, saving time on pre-certifciation and saving money but better identifing issues that may cause failure at the certification lab.
Impedance Stabilization Networks also known as Artificial Mains Networks are the most common transducer to perform conducted emission testing. For testing electrical power lines a Line Impedance Stabilization Network (LISN) is required. To test data lines an Impedance StabilizatioN Network (ISN) is used.
Used between the LISN and measuring device such as an EMI receiver or a spectrum analyzer to protect the unit from high voltage spikes. Most transient limiters are spec'd to meet commerical and military conducted emissions standards (9 kHz to 30 MHz)
Used inbetween close field probes and the measuring device (Spectrum analyzer or EMI receiver) to maximize performance of the probes and help identify problem areas while taking real time measurements.
Close field probes, current probes, voltabe probes and abosrbing clamps are scondary components required in some commercial and military & aerospace conducted emissions standards.
