Step 3: Set Measurement Parameters

Last updated: January 16, 2009

In this step you set up measurement parameters. This configures the measurements so that they are ready to execute in Step 5: INITiate and FETCh Measurements .

Many of the measurements have only generic measurement parameters available, such as measurement count, timeout, trigger arm and trigger source.

There is a command available to set all measurement triggers to single (SET:CONT:OFF ), which is the recommended trigger arm configuration for remote use of the test set. However, if you sent the *RST command in Step 1: Set Up the Test Set , all measurement triggers will already be set to single.

Some measurements have measurement-specific parameters available. Consult the programming reference material available on the Internet to find out more about measurement-specific parameters.

Programming Example

 
830   ! Set all measurement triggers to single
840   OUTPUT Testset;"SET:CONT:OFF"
850   ! Set up the Thermal Power measurement
860   OUTPUT Testset;"SET:WTP:TIM 7;COUN 1"
870   ! Set up the Channel Power measurement
880   OUTPUT Testset;"SET:WCP:TIM 7;COUN 1"
890   OUTPUT Testset;"SET:WCP:INT:TIME .667 MS"
900   OUTPUT Testset;"SET:WCP:FILT ON" ! Turn the RRC filter on
910   ! Set up the Waveform Quality measurement
920   OUTPUT Testset;"SET:WWQ:TIM 7;COUN 1;TSL 1"
930   ! Set up the ACLR measurement
940   OUTPUT Testset;"SET:WACL:TIM 7;COUN 1"
950   ! Set up the Loopback BER measurement
960   OUTPUT Testset;"SET:WBER:TIM 7;COUN 10000"
970   ! Set up the Occupied Bandwidth measurement
980   OUTPUT Testset;"SET:WOBW:TIM 7;COUN 1"
990   ! Set up the Spectrum Emission Mask measurement
1000  OUTPUT Testset;"SET:WSEM:TIM 7;COUN 1"
