Programming a Maximum/Minimum Power Measurement

Last updated: October 28, 2004

This section provides an example program of how to use the maximum/minimum power measurement via GPIB.

The following program example assumes that the mobile station's antenna output is connected to the RF IN/OUT connector, and the mobile station has found service.

The basic procedure to make the maximum/minimum power measurement is as follows:

Make a call. For information on configuring the test set for a call, see Step 4: Make a connection .
Set up the access parameters as needed using the CALL:APARameter commands
Configure the maximum/minimum power setup parameters using the SETup:CMMPower subsystem.
Start the maximum/minimum power measurement using the INITiate subsystem.
Use the FETCh:CMMPower command to obtain the measurement results.

Programming Example

 
10 Mm_pow: !
20      PRINT "Configure  maximum and minimum power measurement parameters" 
30      ! Configure the parameters if neccessary              !
40      ! Here give an example to follow, the value should be adjusted according the
50      ! mobile phone actual parameters. If nothing is changed, the default value will             
60      ! be used. No GPIB command will be called.              
70      OUTPUT Testset;"SETUP:CMMPower:PILot:LEVel:MAXimum 7 DB"              
80      PRINT "Start measure the Maximum / Minmum Power measurement"              
90      !***Obtain measurement results***
100     !
110     OUTPUT Testset;"INITIATE:CMMPOWER"  !Initiates a channel power measurement1 
120     OUTPUT Testset;"FETCh:CMMPOWER?"                
130     ENTER Testset;Integrity,Max_pow,Min_pow 
140     DISP "Test complete" 
150     !***Display measurement results
160     Print_results("Integrity indicator = ",Integrity,"") 
170     Print_results("Maximum Power dBm:",Max_pow,"dBm") 
180     Print_results("Minimum Power dBm:",Min_pow,"dBm/1.23 MHz") 
190     DISP "Test complete"               
200     OUTPUT Testset;"CALL:END"               !Ends the call
210     RETURN
220     Print_results: SUB Print_results(Meas_name$,Res1,Units$)
230     PRINT USING "5X,20A,5X,M4D.2D,1X,15A";Meas_name$;Res1;Units$
240     SUBEND

Returned Values

This query returns an integrity indicator followed by the maximum power result and the minimum power result.
