Problems solved by technology

Other protocols, such as Bluetooth LE, will require additional time slots for sending such acknowledgment (ACK) information, i.e. packets that will essentially double the test time in some cases
A common challenge provided by conventional test methods is the use of sequences that do not contribute direct test values

Abstract

The present invention discloses a system and method for deterministically testing the packet error rate in electronic equipment, including: transmitting a series of data packets from the test equipment to the device under test (DUT) and setting the error-free data packets received a predetermined number; assessing whether the number of data packets received by the DUT without error in a series of data packets is equal to the predetermined number of error-free data packets received; and if not equal to the predetermined number of error-free data packets received, it will have Additional packets are transmitted from the test equipment to the DUT at a power level that produces zero received packet errors in a correctly functioning DUT. Other possible embodiments include evaluating whether the total number of data packets received without error by the DUT in a series of data packets and additional error-free power level data packets is equal to a predetermined number of received error-free data packets; and in response to the DUT receiving Upon said predetermined number of error-free data packets received, an acknowledgment packet is sent to the test device.

Description

Technical field [0001] The present invention generally relates to systems and methods for testing electronic equipment. More specifically, the present invention relates to an improvement of the following system and method for testing wireless devices using a test platform composed of hardware, firmware, and / or software parts, so that a minimum of Feedback. Background technique [0002] Many current handheld devices use "wireless connections" for telephony technology, digital data transmission, geolocation, etc. Although there are differences in spectrum range, modulation method, and power spectral density, wireless connection standards use synchronous data packets to transmit and receive data. Generally, all these wireless connection functions (such as WiFi, WiMAX, Bluetooth, etc.) are defined by industry-recognized standards (such as IEEE 802.11 and IEEE 802.16), which specify the parameters and restrictions that must be followed by devices with the above-mentioned connection ...
