Automatic PerformanceCharacterization IndentifiesPerformance Breakpoints
Industry standard tests define minimumperformance specifications. A thoroughevaluation of a mobile device requiresgoing beyond these baseline testscenarios to identify performancebreakpoints. This test methodology isused to determine the device’soperating margin or to perform acompetitive evaluation. It is crucial to
characterize the worst-case conditionsthe mobile device can tolerate whilestill meeting a user-definedperformance threshold. Since thesetests involve evaluating the deviceversus adverse radio channelconditions, they are focused onparametric receiver evaluation.TASKIT/C2K enables the user tocharacterize performance breakpointsversus an array of dynamic fadingscenarios, receive signal levels, and co-and adjacent channel interferenceconditions.
TASKIT/C2K utilizes an intelligentsearch algorithm to seek outperformance thresholds. UsingAutomatic PerformanceCharacterization (APC), the userspecifies the end points of the rangeto be evaluated and the correspondingminimum performance criteria of thedevice. APC automatically executesonly the tests necessary to reveal themost severe conditions under whichthe performance threshold is satisfied.
UDM - Provides rapid testconfiguration, test automationand mobile device diagnosticanalysis
The Universal Diagnostic Monitor (UDM)enables rapid test configuration byautomatically interrogating the networksettings of the device under test andsetting the corresponding testparameters. This greatly simplifies testsetup by eliminating the need tomanually enter mobile device settingssuch as NID, SID, Channel Number, andBand Class. UDM also captures the keymobile device identity data such asESN, Model Name, Hardware Version,and Software Version that are used tolabel mobile device test results.
In addition, test procedures in CDGStage 2 require run-time control of themobile device under test. Using theUDM’s powerful software router,TASKIT/C2K automates mobile controlwhile the UDM simultaneously monitorsthe device’s performance, resulting incomplete closed-loop automation.
UDM provides a full-featured mobiledevice diagnostic monitor that can beused to display real-time mobile deviceperformance parameters during testexecution. The access it provides tocritical CDMA physical layermeasurements, such as finger energyand Tx/Rx levels is very valuable fortroubleshooting mobile deviceperformance. UDM also captures andcollects air interface messages foranalysis of call processing behavior.
UDM works with TASKIT/C2K to provide:■ Complete closed-loop automated
control of the mobile device■ Automatic test setup of mobile
device configuration parameters■ Detailed display of the mobile
device’s CDMA physical layermeasurements
■ Real-time collection and decodingof air interface messagesUDM enables closed-loop automated testing of a CDMA
mobile device by controlling and monitoring its performance
TASKIT/C2K can be configured to automatically seekand identify receiver performance breakpoints
