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.
Represents shielding effectiveness
greater than or equal to line.

Grayhill maintains a legend library which
contains the most often requested special
legends and many unusual ones. If the legend
is in the library, the cost to utilize this legend in
your keypad configuration is minimal. If the
legend is not available, Grayhill can list the
charges required to add your legend to the
library. In this manner, new legends are added
on a periodic basis. Custom legends to fit your
unique requirements may not be as expensive
as you think, contact Grayhill.
