Programming Example
10 ! PRACH Transmit On/Off Power Measurement Programming Example:
20 ! 5.4.1 Open Loop Power Control in the Uplink
30 !
40 ! This example assumes that the UE is camped to the test set, and in idle mode.
50 ! (The test set must first be configured to allow the UE to camp to the
60 ! test set - sufficient cell power level, proper cell parameters etc.)
70 !
80 ! Ensure that you have properly accounted for the path loss in your system
90 ! using the Amplitude Offset setting.

180 ! Set number of PRACH Ramping Cycles to 1
190 OUTPUT Testset;"CALL:UPLink:PRAChannel:ASUBchannels `000000000001'"
200 ! Set Available Subchannels to 1
210 OUTPUT Testset;"CALL:UPLink:TXPower:LEVel:MAXimum 21"
220 ! Set Maximum Uplink Transmit Power Level to the max power for your UE
230 OUTPUT Testset;"CALL:CONNected:LIMit OFF"
240 ! Set Call Limit State to Off
250 OUTPUT Testset;"CALL:BCCHannel:UPDAtepage AUTO"
260 ! Set BCCH Update Page to Auto so the test set will notify the UE of
270 ! the changes to Cell Parameters.
