4.2.4 Measurement adapters

The measurement adapter type MD 101 as per IEC / EN 61000-4-2 (2001) serves
to verify pulse amplitudes and pulse shapes. It is designed for mounting in the
side wall of a Faraday cage in which an oscilloscope has been installed. This

measurement adapter has the flat impedance curve to well over 1 GHz that is

necessary for the purpose.

Use of this adapter is only worthwhile in conjunction with a test rig that is laid

out in strict conformity with the relevant standard (see section "Verification of

pulse data").

Mounting flange

MD 103 ("Pommerenke" target) is a more advanced coaxial measuring target

with flat response characteristics up to the multi-GHz range. It may be used

instead of MD 101.
