Hardware
The manufacturing testing system involves three major components: MTK test fixture, MTK device
under test (DUT), and an optional PC to monitor and control the MTK test fixture.

Theory of Operation
By default the MTK test fixture executes a set of standard tests when you push the START button. It
sends predetermined test packets to the MTK DUT and expects the MTK DUT to reply to the same
packet with the RX status. LEDs on the test fixture indicate if the test succeeds or fails.
To change the parameters for standard tests, such as channel number, number of packets, packet
length, and so on, it can be done through a control PC. The MTK test fixture provides a RS232 port
and its firmware runs command line protocol. You can use any serial communication application
such as a HyperTerminal to send commands to and receive status from test fixture. See
for details.
