The distortion signals are usually generated or picked up inside of the EUT and the mains cord acts as an antenna. European and international EMC regulations define maximum permissible signal levels and frequency bands for such distortion signals. The distortion signal to be measured is available on a coaxial N?connector that is mounted on the front panel of the NNB 51. For the actual measurement of the distortion signals a measuring receiver can be used. The V?network is part of a complex EMC?test setup that also has been standardised in CISPR 16?2?1 (EN 55016?2?1).Power supplyThe NNB 51 has two separate input connectors for the mains power of EUT and NNB that are located on the rear of the instrument. Earth connectionThe construction of the NNB 51 allows a massive connection to the shielded room wall. Left and right of the front are grounding bars. Additional are located a connection bolt and wing screw on the rear of the LISN. Remote control connectionThe NNB 51 has two built?in remote control circuits and can be controlled with EMI receivers from MEB/Schaffner/Teseq or Rohde & Schwarz.
