Shield Effect Measurement Service

Model No. ssem

KEYCOM has abundant experiences concerning the shielding effectiveness of the device and the cable.
We develop shield effect measurement devices for accurate and practical results.

You want to measure the shielding effectiveness of a sheet specimen.

It measures it by using the following system. Please inform us of frequency bands desired.
Coaxial tube type Effect of shield measurement system (12.0MHz~18.0GHz)
sem01002011015-01
SEM01 complies with ASTM D4935, and is capable of measuring shield effect with plane wave with high accuracy.
·Dynamic range over 100dB.
·153D、39D、20D and GPC7 coaxial type.
·Data can be saved in Excel format, and reproduced graphically.
Waveguide type Effect of shield measurement system (1.0GHz~90.0GHz)
sem02002011015-01
SEM02 measures shield effect at wide ranges of 100dB between 1GHz~40GHz, and 70dB between 40GHz~90GHz.
The incidence angle of the plane wave to the sample changes as frequency changes,
allowing you to measure the correlation between the incidence angle and the shield effect.
 

You want to measure the shielding effectiveness of the cable.

It measures it by using the following system. Please inform us of frequency bands desired.
For cable Effect of shield measurement system
sem03002011015-01
SEM03 is a MIL-C-85485A compliant standard measurement method,
effective for coaxial cable and the multi-core cable evaluation.
It compensates the result with the value of the characteristic impedance.
Crosstalk type For cable Effect of shield measurement system
sem04002021210-03
Complying with the crosstalk method, SEM04 is capable of measuring the shield effect effectively.
·It supports wide variety of cables from coaxial cables to multi-core cables.
·It prevents mismatching caused by the characteristic impedance difference with a 10dB pad.
