Introduction
V-networks are devices that are used to measure disturbance voltages on mains-
dependent loads. For measurements, they are usually inserted between the power
supply and the equipment under test (EUT). The RF port provides the means to con-
nect them to a test receiver and analyze the EUT characteristics.
The main features of a V-network are to:
●
Supply the EUT with AC supply voltage or DC supply voltage.
●
Provide a standardized load impedance.
●
Isolate the test circuit from power supply disturbances.
●
Deliver unsymmetric disturbance voltage generated by the EUT to the test receiver
in a defined manner.
The R&S
ESH3-Z6 in particular is a single phase V-network that corresponds to a 5
µH
inductor. It complies to the requirements specified in CISPR 25.
Unpacking the R&S
ESH3-Z6
1. Carefully remove the R&S
ESH3-Z6 from the box it was delivered in.
2. Check the R&S
ESH3-Z6 for any damage.
Retain the original packing material. If the instrument needs to be transported or
shipped later, you can use the material to protect the control elements and connec-
tors.
