Abstract
Receiver sensitivity is a measure of the lowest signal strength that a receiver can detect. Receiver sensitivity is typically measured by linearly incrementing the received power level until a target packet error rate (PER) is reached. Linear search is slow and can occupy substantial test resources such as test stations and instruments. This disclosure describes techniques to rapidly determine the receiver sensitivity of a device-under-test (DUT) by learning the ensemble characteristics of devices under test, building a packet error rate (PER) model, performing limited-range measurements of the DUT, and using the PER model and the results of the measurements to predict the sensitivity of the DUT. By speeding up the determination of receiver sensitivity, the described techniques reduce test cycle times and enable improvement of the units per hour (UPH) of a factory, resulting in a lower cost of owning and operating test stations and instruments.
