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 52. 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 supply and connectorsThe NNB 52 has two separate input connectors for the mains power that are located on the rear of the instrument. The CEE mains socket 4x32 A is used to power the EUT. This IEC mains connector is used to supply the required power for the control circuit of the LISN. It also supplies the AC power for the built in blower. Earth connectionThe construction of the NNB 52 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 52 has two built?in remote control circuits and can be controlled with EMI receivers from MEB/Schaffner/Teseq or Rohde & SchwarzStandards applied: CISPR 16?1?2, MIL?STD?461D and EFrequency range: 9 kHz to 30 MHzAttenuator (build?in): 10 dBNNB operating voltage: 100 to 120 V / 220 to 240 V, 50 to 63 HzEUT operating voltage: max. 400 VEUT frequency: DC to 63 HzEUT phase detection function (LED): >48 VEUT operating current: max. 4x32 ALine impedance: 50 ? || (50 μH + 5 ?)Nominal output impedance: 50 ?RF connector type: N femaleArtificial hand / connector type: 510 ? + 220 pF / 4 mm bananaLimiter: approx. 136 dBμV typ., switchableArtificial PE: switchableConnector type for two wire remote control: KFV 60Connector type for four wire remote control: D?sub 25 pinsSize (W x D x H) without mounting parts: 450 mm x 375 mm x 265 mmSize (W x D x H): 480 mm x 485 mm x 275 mmWeight: approx. 23.3 kgPart number Description253551 NNB 52 Four?line?V?LISN for 32 A97?253550 NNB 5x?TC Traceable calibration (ISO17025) order only with new device 232080 LE 216 Control cable SCR 35xx / NNB xx243134 LE 234 Control cable SMR 45xx / NNB xx
