- Fourline-V-LISN Type NNB-4/63TL
The
Fourline-V-LISN, Type NNB-4/63TL, is suitable for the normative
measurement of unsymmetrical interference voltages at high power
levels. The LISN is manufactured according CISPR-16 and VDE 0876 part
1. Next to the fourline LISN it also contains a complete twoline V-LISN
with a switchable artificial PE 50 Ohm // 50 µH and an artificial
hand 220 pF + 510 Ohm.
Interference-free fans are cooling the unit, causing a forced air
circulation. The LISN can be remote controlled by TTL signals via the 9
pin Sub-D connector at the backpanel. It is free of choice, which path
is to be measured. All other paths, which are actually not measured,
will be connected to ground with the correct impedance value. The
frequency variation at the output is compensated. All common receivers
and spectrum analyzers with 50 Ohm input impedance can be connected.
The LISN is fully traceable calibrated in respects of impedance and the
insertion loss on the way from the DUT to the output connector.
