Programming Example
This programming example assumes that a call has been originated from the mobile station or the test set.
10 Test_set=714
20 OUTPUT Test_set;"CALL:TCHannel:CMODe:LSPeech:CHANnel AFS"
30 !Sets the Logical Speech Channel to AFS (Adaptive Full)
40 !-one of the two AMR Logical Speech Channels.
50 OUTPUT Test_set;"CALL:TCHannel:CMODe:AFSpeech:CODec AFS6700,AFS7400,AFS7950,AFS10200"
60 !These four codecs are now the Active Codec Set.
70 OUTPUT Test_set;"CALL:TCHannel:CMODe:AFSpeech:CODec:CURRent AFS6700"
80 !If a call does not exist, this codec will be the initial codec used when a call is made.
90 !If a call does exist, then the codec automatically switches to this codec.
100 !Note that the current codec must be a codec defined in the Active Codec Set.
110 OUTPUT Test_set;"CALL:TCHannel:CMODe:AFSpeech:CODec:THReshold 6,1.5,12,1.5,18.5,2"
120 !Sets the threshold and hysteresis values in the following order:threshold 1,
130 !hysteresis 1, threshold2, hysteresis2, threshold 3,hysteresis 3.
140 OUTPUT Test_set;"SETup:IFERror:TIMeout:STATe OFF"
150 !IFER measurement will not timeout.
160 OUTPUT Test_set;"SETup:IFERror:CONTinuous OFF"
170 !Configures the IFER measurement to Single Trigger.
180 OUTPUT Test_set;"SETup:IFERror:COUNt 150"
190 !Sets the number of speech frames to measure to 150000,
200 !the minimum recommended by the standard.
210 OUTPUT Test_set;"SETup:IFERror:LDControl:AUTO ON"
220 !Automatically determined the number of speech frames needed to wait
230 !for the complete loopback type I. IFER measurement will not start if
240 !loopback type I is not supported by the mobile station.
260 OUTPUT Test_set;"READ:IFERror?" !Start and obtain all IFER measurement results.
270 ENTER Test_set;Integrity,Speech_frames,Fer,Fec
280 PRINT "Integrity",Integrity
290 PRINT "Speech Frames Tested",Speech_frames
300 PRINT "Frame Error Ratio",Fer
310 PRINT "Frame Error Count",Fec
450 END
