    By design, V-networks exhibit high leakage currents. Moreover, by principle, such a device does not have standard-compliant isolation and there is no fuse in the measuring circuit (the R&S ENV4200 only has a fuse in the auxiliary circuit of the ventilation system). Hence, users must be protected against touching conductive parts that may carry live mains voltage.

    Observe the notes in the "Safety instructions" chapter and the protective earth instructions in the "Protective earthing" section! In general, when the R&S ENV4200 is operated, make sure that the air supply is not obstructed from above or below. Since the device has air vents located on the bottom side, it must be placed upon a nonflammable base (e.g.

    ) of the R&S ENV4200, so that even in the case of a faulty device under test, i.e. in the event of a short circuit, the housing voltage is below 4 V.

  • Page 31: Ac Supply

    R&S ENV4200 Preparing for Use 4.4 AC Supply Electric shock due to incorrect power supply. Due to the design, V-networks do not have standards-compliant insulation, do not have a fuse in the measuring circuit and exhibit high leakage currents. In order to protect the user from contact with electrically live instrument parts, the power supply connection of this V-network must be made by experienced electrically skilled personnel.
  • Page 32 R&S ENV4200 Preparing for Use V-networks such as the R&S ENV4200 may also not contain any power fuses. Therefore, the connected mains supply must be sufficiently fused. The maximum permissible continuous current voltage is 200 A. Accordingly, the power supply must be protected at 200 A.

  • Page 33: Connecting The Rf Reference Ground

    R&S ENV4200 Preparing for Use 4.5 Connecting the RF Reference Ground The V-network is connected to the PE protective earth conductor of the power supply through the protective earth conductor terminal. However, this is unsuitable as an RF reference mass for interference voltage measurement. Therefore, the V-network must be connected to an appropriate RF reference ground to obtain reproducible and correct measurement results.

  • Page 34: Avoiding Grounding Loops

    R&S ENV4200 Preparing for Use Make sure that the RF reference ground is not impacted by disturbance voltages (e.g. from an industrial network) when the protective earth conductor is connected to the protective earth. If this is the case, the protective earth must be connected via a PE choke.

    V-network corresponds to the local AC supply voltage. The R&S ENV4200 can be set for two different nominal AC supply voltages: 115 V and 230 V. In the 115 V setting, the nominal AC supply voltage range is 100 V to 120 V. In the 230 V setting, the nominal AC supply voltage range is 220 V to 240 V.

    R&S ENV4200 Preparing for Use Fig. 8 Low-temperature socket, fuse holder and line voltage selector After selection of the voltage range, connect the V-network to the supply voltage using the supplied power cable. If the V-network is correctly connected, one of the four green LEDs for displaying the test path should light up (depending on the position of the LINE SELECTION rotary switch).

  • Page 38: Db Attenuator

    R&S ENV4200 Preparing for Use 4.8 10 dB Attenuator The built-in 10 dB attenuator attenuates the disturbance voltage emitted by the EUT by 10 dB. The attenuator ensures the 50 Ω termination required to meet the impedance tolerance, improves matching with the test receiver and provides a sufficiently high ohmic internal resistance to ensure correct functioning of the pulse limiter.
