EAS12 is a portable version of the “Lens Antenna Method, Vertical Incidence Type
Electric Wave Absorber, Return Loss Measurement System: EAS07”, that allows you to perform your measurement in the field.
Its movable antennas easily detect the influences caused by the seams in the electric wave absorbers.
Unlike coaxial or waveguide type, errors by air gap do not occur because the sample is not capsulated in the fixture. Despite its compact dimensions, your sample can be measured with plane wave because the lenses are attached to the antennas, providing high measurement accuracy. Samples can be smaller than conventional systems because they can be placed in the vicinity of the antennas.
Standardization:
JIS R1679 : 2007
IEC 62431 : 2008
• * The higher the measurement frequency is, the smaller the samples can be.
*By applying the gate beyond the lenses closer to the sample, electric wave absorption rate as low as approx. -50dB is measurable, using a standard vector network analyzer.
