age and some control lines have to be routed through the wall of the shielded room.
You can also use a direct connection without a filter, e.g. when you use the R&S
ESR
in a shielded room. In that case, you can use the following cables.
●
R&S ESH2-Z5: EZ-5, EZ-13, EZ14

R&S ESH3-Z5: EZ-6, EZ-14

R&S ENV216: EZ14

Transducers
A transducer is often connected ahead of the R&S
ESR both during the measurement
of useful signals and EMI and converts the useful or interference variable such as field
strength, current or RFI voltage into a voltage across 50
Ω
. Because most transducers
such as antennas, probes or current probes have a characteristic frequency response,
it is necessary to correct the measurement results by the frequency characteristics of
the transducer. These characteristics are defined in a transducer factor or transducer
sets. The transducer factor can be stored in the R&S
ESR and automatically has the
correct unit during level measurement.
