Shielding effectiveness
Results shown are typical for a standard Grayhill
Series 84S keyboard. A conductive gasket will
generally increase the shielding, depending on
the size and shape of the gasket and its material.
Data derived for E-Field Radiation.
test method:
Measurements were made with the keyboard
mounted to a brass plate, which in turn was
mounted to a shielded enclosure containing the
receiving equipment. A signal generator provided
the frequency source that was radiated from the
transmitting antenna to the enclosed receiving
antenna. The spacing between antennas was
maintained constant throughout the frequency
range. The effectiveness rating is determined
by establishing a reference reading without
obstruction between the two antennas and
determining the difference between that reading
and the test setup reading.
note:
When measured in actual equipment, shielding
effectiveness is determined by many factors.
This method accurately represents the shielding
effectiveness of the Grayhill Series 84S under
Ideal test conditions.
