Test Steps and Description
Sensitivity Search
Performs PER test using the one of the three search modes below to sweep through the power values
set. Use this step to determine the lowest output power the DUT can support to meet the PER limit.
Step Settings
– Search Mode: Select one of the three options available.
– Binary Sensitivity (Fastest): Perform binary searches for the PER sensitivity level.
– Linear Sensitivity (Slowest): Search for the PER sensitivity level by sweeping from maximum to
minimum power. This search will stop when it discovers the ‘Last Pass’, the last PER value that
produces a ‘Pass’ verdict.
– Mid-point Bi-directional: Search for the PER sensitivity level using a combination of binary and
linear sensitivity searches. From the first break point of the binary search, it will sweep in a linear
pattern for the ‘Fail’ point and report the ‘Last Pass’ value.
The Early Fail Count, Delay between Step, Reconnect Retries, and Preferred Mode parameters are as
described under
test step.
