Introduction
The CY3631 – WirelessUSB™ Manufacturing Test Kit (MTK) enables Cypress’s customers to test
their WirelessUSB products in a manufacturing environment without the use of expensive RF test
equipment. The highly integrated nature of the WirelessUSB radio device ensures that there are
very few errors in the assembly process. The device is tested before it leaves the Cypress factory.
There are only a few critical components on the customer’s board that affect the operation of the
radio. Most of the possible assembly level failures (missing components, open/cold solder joints, and
pin-to-pin shorts) cause a large reduction in transmitted power or receive sensitivity if the unit
functions. A simple functionality test at maximum range eliminates most bad units.
The MTK prevents testing each unit over long distance and interference between multiple units that
may be on the test floor simultaneously. This is because the MTK is designed to simulate a limit-of-
operation condition using a shielded test fixture and enclosure.
