Brief Description

The R&S®ENV4200 200 A four-line V-network meets the requirements of CISPR 16‑1‑2, EN 55016-1-2, ANSI C63.4 and FCC Part 15 for V-networks with an impedance of 50 μH || 50 Ω in the frequency range from 150 kHz to 30 MHz. It is used for measuring RFI voltages on AC and DC supply connections of EUTs carrying very high currents. It is based on aircore inductances and contains an artificial hand and a pulse limiter.

Features & Benefits

Air-core design and artificial hand

The R&S®ENV4200 200 A four-line V-network is based on air-core inductances and contains an artificial hand in order to mimic the influence of the user’s hand while measuring the disturbance voltage.

Built-in 10 dB attenuator pad

To ensure standard impedance irrespective of the measuring receiver's input attenuation, the R&S®ENV-4200 is equipped with a 10 dB attenuator pad.

Built-in pulse limiter (can be switched off)

A built-in pulse limiter that can be switched off protects the measuring receiver's input.

Automatic temperature monitoring

When the temperature inside the housing reaches about +50°C, the fans of the R&S®ENV4200 automatically switch on. This protects the V-network in case of a high constant current load.

Remote control with TTL levels (compatible with Rohde&Schwarz measuring receivers)

TTL control inputs that can be driven by controllers or Rohde&Schwarz measuring receivers are provided for remote control of phase selection in an automatic test system.
