5 1.3 Radio Signal Analyzer User guide Before starting test, read carefully the Radio_Signal_Analyzer User guide (available on ), it will be easier to use Radio_Signal_Analyzer and to find all things after that Verdict Type EVALUATION All requirements are manual verdict and have to be updated by the operator. Check each "Covered requirement" table to know the manual verdict and the "Manual Verdict" explanation to know if this verdict is "FAILED" or "PASSED". TOOL-ANALYSIS All requirements are automatic verdict and will be updated automatically by Radio_Signal_Analyzer. MEASUREMENT All measurement are automatic and will be updated automatically by RSA Checklist Information All information from the checklist have to be filled in properly before starting test. Radio_Signal_Analyzer should be configured according to this checklist (RCx, modem type, ID/KEY values,...). Some checklist information will be needed all test long. 4

15 PRS-UNB-MODEM-10 Frequency Steps TOOL-ANALYSIS 3 Results Be careful, when saving the measurement, the result folder will be cleared. If the manual verdict is fail, add a note in the comment part to explain why (for example : The command doesn t work). Choose the proper verdict and fill in all "comments" line for all Pre-requisites in the "Info / Prereq / Equipment / Verdicts" window ("Prerequisites" subwindow). All commands have to be validated to have a "PASS" verdict and written in the comment part if it works properly. Export results when all requirements have been tested (all verdicts should be "FAIL", "INFO" or "PASS") : In "Info / Prereq / Equipment / Verdicts" window, Choose "Export Results" Open the result folder Select your DUT picture Select the I/Q record The SigfoxVerifiedCertification.tar.gz will contain all information (verdicts, comments, information) and shouldn t be modified in any way. All verdicts : "INCONCLUSIVE", cannot be validate with this equipment (due to the equipment s limitation). 14
