About This Product
Easy to build a test environment in a limited space.
･ Lisn is required to perform stable and reproducible obstruction noise.
･ By inserting Lisn into the power line, the impedance of the power line as seen from the EUT is constant.
When measuring the conductive obstruction noise released through the power line, the measured value is affected by the impedance of the power line.
If the impedance is low, the amount of noise will be measured, and if the impedance is high, the noise amount will be measured in large amounts. In this case, the measured value is not universal or reliable.
Therefore, it is necessary to make the power line impedance constant in order to perform stable and reproducible obstruction noise measurement.
By inserting the line impedance stabilization circuit network (LINE IMPEDANCE STABILIZATION Network) into the power line, the impedance of the power line as seen from the EUT is constant. However, the power line impedance has a frequency characteristics, but its characteristic curve is specified by Cispr.
The MPW201B circuit system adopts <50Ω/50 μh, V type> conforming to Cispr16-1. The measurement frequency range is 150kHz to 30MHz, and the power supply available is a single phase, a maximum voltage 250 VAC, 50/60Hz, and a rated current 15A.
As shown in the equivalent circuit, the obstruction noise released from the EUT is led to a 50Ω input transformer through a high -pass filter composed of capacitors and resistance, and is entered into EMI specification analysis MSA438E/538E/558E.
The disturbing noise measures the L1 terminal and the N terminal of the power supply individually, but a high -voltage transgaint pulse may occur when switching the measurement line. This Transent Pulse has a built -in 10DB Attenator and a transformed remitter with a diode to protect the spectrum analyzer.
