Introduction
EM5040/5040A/5040B
Line Impedance Stabilization Network is a kind of
（

||50Ω
V type LISN. This product can provide stable impedance from 9 kHz to 30 MHz RF range for
DUT and reference. At the same time, it isolated the useless signal from the electric network to
measurement circuit and coupling the interference voltage of the DUT to the input port of the
measurement receiver. The product’s performance is compliant with standard requirements of
CISPR16-1-2 for V-networks. It suits conducted disturbance voltage measurement for single phase
equipment well. The standard BNC output port and 50Ω output impedance make the device
compatible to the measurement equipment such as receiver and spectrum analyzer of any
manufacturer. The artificial hand of the product can simulate the handle device to measure.
EM5040
is a type of single phase standard LISN.
EM5040A
has a limiter (with attenuation of
10dB) and an optional 150 kHz high pass filter. Users can choose to start from 9 kHz or 150 kHz
according to corresponding standard. The built in transient limiter can effectively protect receiver or
spectrum analyzer from damage caused by large signal. Users can connect EM5040A safely to
those devices without other limiter.
On the bases of EM5040A,
EM5040B
is added the function used for common mode and
differential mode measurement, which will provide assistance for EMI debugging, especially for
EMI filter.
EM5040C
LISN is a type of single line
（

|| 50Ω LISN. This product can provide
stable impedance from 100 kHz to 200MHz range for DUT and reference. At the same time, it
isolated the useless signal from the electric network and measurement circuit and coupling the
interference voltage of the DUT to the input port of the measurement receiver. It is compliant with
VDE0876 Part1 (onboard power-supply systems), VDE0879 Part2, CISPR16-1-2(Low-impedance
power supplies), CISPR25 and EMC Directive 95/94/EG, DIN40839, IS07637, MIL-STD-462,
MIL-I-6181D, MIL-E-55031, DEF STAN59-41 and DO 160.
