Introduction
There are two basic types of the artificial mains network (AMN), the V-network (V-
AMN) which couple the unsymmetric voltages, and the delta-
network (Δ-AMN), which
couple the symmetric and the unsymmetric voltages separately.
The R&S ENV4200 four-line V-network is used to measure disturbance voltages on
mains-dependent loads.
Its main functions are as follows:
●
Supply the equipment under test (EUT) with AC supply voltage or DC supply
voltage
●
Provide a standardized load impedance
●
Deliver the unsymmetric disturbance voltage generated by the EUT to the test
receiver in a defined manner
●
Decouple the test circuit from mains disturbances
The R&S ENV4200 V-network is built with air-core inductances (50
μH and 250 μH)
and conforms to the requirements specified in CISPR 16-1-2.
Additional equipment:
●
Artificial hand
●
10 dB attenuator in decoupling branch
●
Pulse voltage limiter at measurement output
●
Remote control interface
●
Separate power supply for control electronics and remote control interface
The V-network can be operated manually or under remote control via a TTL interface.
