SYSTEM AND METHOD FOR DETERMINISTIC TESTING OF PACKET ERROR RATE IN ELECTRONIC DEVICES
First Claim
1. A method of testing a communication device comprising:
- transmitting a series of data packets from a testing device to a device under test (DUT);
setting a predefined number of received error-free data packets;
evaluating whether a number of data packets from the series of data packets received error-free by the DUT equals the predefined number of received error-free data packets;
transmitting additional data packets from the testing device to the DUT if said number of data packets from the series of data packets received error-free by the DUT does not equal the predefined number of received error-free data packets;
evaluating whether a total number of said number of data packets from the series of data packets and the additional data packets received error-free by the DUT equals the predefined number of received error-free data packets; and
transmitting a confirmation data packet to the testing device in response to reception by the DUT of said predefined number of received error-free data packets.

Abstract
A method and system for testing packet error rate in electronic devices by transmitting a series of data packets from a testing device to a device under test (DUT) and setting a predefined number of received error-free data packets; evaluating whether a number of data packets from the series of data packets received error-free by the DUT equals the predefined number of received error-free data packets and transmitting additional data packets from the testing device to the DUT, at a power level known to produce zero received-packet errors in a correctly operating DUT, if the number of data packets from the series of data packets received error-free by the DUT does not equal the predefined number of received error-free data packets. Additional possible embodiments include evaluating whether a total number of data packets from the series of data packets and the additional error-free-power-level data packets received error-free by the DUT equals the predefined number of received error-free data packets and transmitting a confirmation data packet to the testing device in response to reception by the DUT of the predefined number of received error-free data packets.
