Manufacturing Test Plan Overview for IMT tool
1. Test initialization and Product identification
PCB serial number, product part number, and MAC address are established.
A bar code scanner or the keyboard can be used to enter this information
By default the information is divided between two codes. The first (bar) code
contains the PCB serial number. The second bar code contains the product part
number and half the Mac address.
2. DUT insertion
Depending on the type of DUT, the software waits for the DUT to be attached to
the set-up. If the DUT is not responding, the user is offered an escape by pressing
the ABORT button.
Alternatively the user is asked to insert the DUT and press the NEXT button. The
software then switches the DUT on, and continues with the testing.
3. System test
Properties of the operating system, including the version number, are determined
and tested for compatibility. The versions of a number of DLLs and other system
files are checked for compatibility as well.
4. Firmware and Driver Compatibility test
The MTFW version number is tested for compatibility.
5. Transmitter verification
A quick test is performed to verify the transmit function of the DUT. If the DUT
passes this test, the following is true: the test system can communicate with the
DUT firmware. The DUT can transmit RF signals with approximately the right
frequency and amplitude.
6. Frequency accuracy
The carrier frequency accuracy of the DUT is determined at the center channel.
The sum of the measured deviation plus the maximum instrument error must be
less than the limit set by the 802.11 standard
7. Receiver verification
The capability of the receiver circuitry to receive and demodulate 802.11 packets
is verified. If the DUT passes, the following is true: the receiver functions
correctly and the receiver sensitivity(PER) is within limits.
As part of this test the GRT output power is measured, the RF isolation between
GRT and DUT is verified, and interference from other 802.11 sources is detected.
