    Be sure to observe the requirements in the safety instructions chapter as well as the section on protective earth grounding! In general, when the R&S ENV432 is operated, make sure that the air supply is not obstructed from above or below. Since the device has air vents on the bottom side, it must be placed on a nonflammable base (e.g.

    ) on the rear panel of the R&S ENV432. In this manner, the housing voltage will remain under 4 V even in case of a faulty EUT, i.e. in the event of a short circuit.

  • Page 32: Ac Supply

    Additional measures must be taken to protect the user against direct or indirect contact. V-networks such as the R&S ENV432 may also not contain any power fuses. Therefore, the connected mains supply must be sufficiently fused. If the EUT is operated on the single-phase SCHUKO socket outlet (EUT 1), the maximum permissible constant current is 16 A and the AC supply must thus be fused for 16 A.

  • Page 33: Connecting The Rf Reference Ground

    R&S ENV432 Preparing for Use Connecting the RF Reference Ground The V-network is connected via the power connector to the protective earth conductor (PE) of the mains supply; however, this is not suitable as an RF reference ground for measuring disturbance voltages. 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 ENV432 Preparing for Use 4.5.1 Avoiding Grounding Loops To avoid grounding loops, the V-network should be grounded only once in the test setup, if possible. An example of using a protective earth choke (PE choke) was already given above (ensuring that the RF reference ground is not impacted by disturbance voltages from an industrial network).

    V-network corresponds to the local AC supply voltage. The R&S ENV432 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 ENV432 Preparing for Use Fig. 6 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 ENV432 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.
