1. For measuring shielding effect of sheet sample
1.1. Shield Effect Measurement System, Coaxial Tube Type (10.0kHz~18.0GHz) [SEM01] | 1.2. Shield Effect Measurement System, Waveguide Type(1.0GHz~90.0GHz) [SEM02] | ||
SEM01 complies with ASTM D4935, and is capable of measuring shield effect with plane wave with high accuracy. Dynamic range over 100dB. Available 153D、39D、20D and GPC7 coaxial type. Data can be saved in Excel format, and reproduced graphically. |
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. |
2. For measuring shielding effect of cable
2.1. Shield Effect Measurement System for Cable [SEM03] | 2.2. Shield Effect Measurement System for Cables, Crosstalk Type [SEM04] | ||
SEM03 is a MIL-C-85485A compliant standard measurement method, effective in evaluating coaxial cable Correction by the value of characteristic impedance can also be performed. |
The system is based on the crosstalk method and can easily measure the shielding effect. It can be used for both coaxial cables and multi-fiber cables. The use of 10dB pads prevents mismatching due to differences in characteristic impedance. |
