NSG 3040 EMC test system
14.7.3 MD 310 SOW pulse current probe set
The MD 310 probe is specially adapted to verify Damped Oscillatory Wave
current pulses as specified in IEC/EN 61000-4-18 or ANSI/IEEE C37.90.1 and
their derivates.
The main advantage of the MD 310 current probe is, that the measuring system
is physically isolated from the circuit under test.
The MD 310 current probe is ready to use. It comes with a pre-mounted coaxial
cable as well as the conductor carrying the SOW current to be measured. The
BNC-end plug needs to be connected to the high-impedance input or 50 Ω input
of an ordinary memory oscilloscope. Then the conductor carrying the SOW
current to be measured needs to be connected between the EUT supply. The
resulting voltage wave shape on the oscilloscope will then be an authentically
reproduction of the actual current wave shape within the given accuracy.
Optional FISCHER connectors are available for matching the safety banana con-
nectors of the shorting cable to the HV output of the generator. For monitoring
the EUT current during a test, an additional IEC adaptor with the safety banana
connectors can be connected to the generator EUT output for observation of
one lead at a time.
