1. Summary
EM5018 Absorbing Clamp is mainly used for measuring the power interference signal from the
power cable of EUT, frequency ranging from 30MHz to 1000MHz. EM5018 is in accordance with
CISPR 16-1-3 regulation, with operating current over 25A, pore diameter around 20mm, can be
widely used in the measurement of testing the interference signal of the standard power supply cable
like CISPR 13/EN 55013, CISPR 14-1/EN 55014-1.
2. Product and Accessories
①Gasket Clamp: can increase the measurement accuracy when the diameter of cable under test
is less than 6mm. If the diameter is over 6mm, remove the gasket clamp.
②EUT port: used to connect the cable of EUT.
③Spring catch: locked during measurement
④RF output port: interference signal output port, connecting with measuring devices like
receiver.

4．Typical application configuration diagram of power disturbance
measurement
When the diameter of the cable under test is over 6mm, remove the gasket clamp of the
absorbing clamp, which can increase precision when the cable is thin
Important tips during measurement:
Please lock the absorbing clamp.
The side with EUT mark should be close to the EUT, absorbing clamp cannot be installed
reversely.
Find maximum value of all frequency point by moving absorbing clamp on the trail.
Interference signal measured P (dB(pW)) = Voltage measured V(dB(uV)) + Clamp factor
(dB(pW/uV))
