family of PSoC products is one of the most secure families of its kind on the market today, regardless of how they are used.
There may be methods, unknown to Cypress, that can breach the code protecti on features. Any of these methods, to our
knowledge, would be dishonest and possibly illegal. Neither Cypress nor any other semiconductor manufacturer can
guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”
Cypress is willing to work with the customer who is concerned about the inte grity of their co de. Code prot ection i s constantly
evolving. We at Cypress are committed to continuously improving the code protection features of our products.

1. Introduction
1.1 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 joint s, 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-ofoperation condition using a shielded test fixture and enclosure.
1.2 Kit Contents
The MTK contains the following items:
■ MTK test fixture
■ 12 SubMiniature version A (SMA) to SMA coaxial cables
■ 24 SMA to SMA coaxial cables
■ SMA-F to SMA-F adapter
■ Six fixed 50-ohm attenuators: 1 dB, 2 dB, 4 dB, 7 dB, 15 dB, and 30 dB
■ SMA 2.4-GHz antenna
■ Power supply transformer
■ CD with firmware source and documentation

2. Kit Operation
2.1 Hardware Setup
1. Attach the supplied antenna to the SMA pass-through connector of the test chamber.
a. Use the SMA pass-through that is furthest from the sides of the chamber if there are more
than one.
b. Orient the antenna at either 0 degrees or 90 degrees. It is important that you keep the same
relative position and orientation of the fixed antenna and the device under test (DUT) for all
tests. These can affect the signal strength. See Figure 2-1.
2. Attach one coaxial cable to the matching SMA outside the cha mber.
a. Make certain to connect to the same pass-through that has the antenna installed.
3. Attach the other cable to the SMA on the MTK test fixture.
a. Use an appropriate SMA torque wrench on all SMA connections or tigh ten your finger to avoid
damaging the connectors. It is important that the connections are tight enough so that proper
contact is made. Loose connections can impact the repeatability of the test.
4. Place fixed or variable attenuators between the two cables.
a. Determine the correct attenuation.
b. If you are using the supplied fixed attenuator s, use the female-to-female adapter to conn e ct
the male end of the attenuators to the cable.
5. (Optional) Attach a serial cable (not included) be tw ee n th e MT K te st fixtu re an d the com p ut er.
a. If a computer is used for setup or testing, attach it to the serial port with a serial cable or a
USB-to-serial adapter cable (not included).
b. See Appendix - A on page 19 for the default setting of the serial port on the test fixture.
6. Insert the power plug into the MTK test fixture.
a. The MTK test fixture goes through a power-on self-check, which lights all of the LED
indicators. After the green PASS light is lit, the test fixture is ready for use or to receive serial
commands.
