The HM6050-2 Line Impedance Sta-
bilization Network (LISN) meets standards
VDE 0876 and CISPR Publ. 16. It contains air
core inductance coils and features an
Artificial Hand and a PE simulating network
which can be bridged.
Conducted emissions on AC power lines,
which are typically generated by electrical
equipment, can be verified with the help of a
LISN together with a Spectrum Analyzer/EMC
Receiver. The DUT (device under test) must
be connected directly to the LISN. Inside the
LISN the power lines are terminated with a
well-defined impedance network, against
each other and against ground.
The HM6050-2 Line Impedance Sta-
bilization Network (LISN) in principle is a
filter network. Through a low pass filter the
DUT is connected to the AC power lines.
The LISN also presents a well-defined
impedance to the signal. For measurements
with a Spectrum Analyzer/EMC Receiver
the EMC signal is available after having
passed a high pass filter.
Two identical networks provide the asym-
metric noise emission signals of the DUT’s
power lines L1 and N. The user can choose
between the signals, the selected one will
be available at the HM6050-2’s test signal
outlet. The stabilization network (simulation
for the AC power lines) is arranged in form
of a "V".
When working with a Spectrum Analyzer/
EMC Receiver it is highly recommended to
enable the built-in Transient Limiter of the
HM6050-2.
