- Page 2 The highly integrated nature of the WirelessUSB radio device is such that there is very little that can go wrong in the assembly process. The device itself 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.

Page 17: Appendix C - Calibration
Photo #6 – Calibration Setup, below. If the variable attenuator used does not have sufficient range, it may be necessary to install both the variable and some fixed attenuation. The amount of fixed attenuation will have to be determined by trial and error. Cypress Semiconductor Corporation Page 17/20... - Page 18 Once a base line is established by passing the test, the attenuation is increased and the test repeated. Doing this several times, increasing the attenuation each time, will eventually reach the level where the golden DUT fails the test repeatedly at a given Cypress Semiconductor Corporation Page 18/20...
- Page 19 Finally, the golden DUT should be tested once more with the fixed attenuation installed to ensure that the setup is still working. The test should pass repeatedly. If it does not, check the attenuation value and all connections again. Cypress Semiconductor Corporation Page 19/20...
