Parameter Descriptions

35. RXD Sensitivity FER Search Specification (%)

35. RXD Sensitivity FER Search Specification

(%)

This parameter sets the FER specification that will be used to

determine when to stop TEST_47 - RXD Sensitivity Level Search

Entering larger numbers in this parameter lowers the number of

frames that must be measured in order to achieve the 95-percent

confidence level and stop the test. Larger numbers therefore shorten

test time. As an illustration of this process, an FER of 0.5 percent

requires that at least 600 frames be measured at each power level, an

FER of 1.0 percent requires that at least 300 frames be measured, an

FER of 2.0 percent requires that at least 150 frames be measured, and

so forth. This parameter is used only in TEST_47 - RXD Sensitivity

Level Search and not in TEST_39 - RXD Sensitivity & Dynamic Range.

Example

If you wish to perform an FER sensitivity search to an FER sensitivity

specification of 2.0 percent, enter 2.0 as the value.
