Programming a Code Domain Measurement

Last updated: January 16, 2009

This section provides examples of how to make code domain measurements via GPIB.

General Code Domain Programming Example
Program Example: 5.2D UE Relative Code Domain Power Accuracy for HS-DPCCH and E-DCH (lab application or feature-licensed test application only)
Program Example: 5.13.2B Relative Code Domain Error with HS-DPCCH and E-DCH (lab application or feature-licensed test application only)

The basic procedure is as follows:

Set the code domain setup parameters as desired using the SETup:WCDomain commands.
Use the INITiate:WCDomain command to start the measurement.
Use FETCh:WCDomain? queries to obtain the measurement results.

General Code Domain Programming Example

The following program example assumes that the mobile station's (UE's) antenna output is connected to the RF IN/OUT connector, and that the mobile station is synchronized to the test set and is transmitting an uplink signal.

 
10    ! Set trigger mode to single for the Code Domain measurement
20    OUTPUT 714;"SETup:WCDomain:CONTinuous OFF"
30    ! Set a timout value of 5 seconds and enable the timeout state
40    OUTPUT 714;"SETup:WCDomain:TIMeout 5"
50    ! Set the trigger source to automatically select the appropriate
60    !  trigger
70    OUTPUT 714;"SETup:WCDomain:TRIGger:SOURce AUTO"
80    ! Set the timeslot to be measured
90    OUTPUT 714;"SETup:WCDomain:TSLot 7"
100   ! Initiate the Code Domain measurement
110   OUTPUT 714;"INITiate:WCDomain"
120   ! Fetch the integrity indicator and the results of the measurement
130   OUTPUT 714;"FETCh:WCDomain:INTegrity?;BETas?"
140   ENTER 714;Integrity,Bc1,Bd1,Bd2,Bd3,Bd4,Bd4,Bd5
150   ! Check the integrity indicator to ensure the results are valid
160   IF Integrity<>0 THEN
170     PRINT "Measurement failed."
180   ELSE
190   ! Process the measurement results.
200   END IF
210   END

Integrity stores the returned integrity indicator value (see Integrity Indicator ); 0 means a successful measurement with no errors.
Bc1 returns the relative amplitude level for the DPCCH (bc).
Bd1 returns the relative amplitude level for the DPDCH (bd1).
Bd2 - Bd6 returns "NAN" (Not A Number). These are reserved for use in the future.
