EMC test is a far-field testing, which gives frequency information about which frequency points are overstandard, but there is no location information. Near-field measurement sits very convenientally for interference positioning, and even accurate to the IC pin to specific line, thus determining the cause of interference.
Conduction interference is mainly based on frequencies below 30MHz, for the power terminal conduction interference mainly measures the device under test along the power cord to the power supply network of the harassment voltage, but also includes through the signal line to the other surrounding equipment transmitted to the harassment signal.
