Methods for testing receiver sensitivity of wireless electronic devices

A method of using a test system to test a device under test, comprising:

• with the test system, transmitting radio-frequency test signals at a plurality of power levels to the device under test, wherein the radio-frequency test signals include a test trigger signal;
• with the test system, receiving test data from the device under test, wherein the test data includes a measured trigger signal;
• with the test system, determining whether the test data is synchronized with the test signals by comparing the measured trigger signal to the test trigger signal;
• and
• in response to determining that the test data is unsynchronized with the test signals, calibrating the test data by adding offset data to the test data so that the test data is synchronized with the test signals.

• and
• in response to determining that the test data is synchronized with the test signals, identifying a receiver sensitivity for the device under test using the test data, wherein the test data includes error rate data, and identifying the receiver sensitivity comprises:
• comparing the error rate data to a predetermined threshold;
• and
• identifying a power level in the plurality of power levels at which the device under test measures error rate data exceeding the predetermined threshold.
