Function

Queries the average value of the F-FCH Eb/Nt (the energy per bit to total noise) during the FER measurement when FPC mode 000 is enabled on the test set. It is used to determine the Eb/Nt Pass/Fail result (see FETCh:CFERror:EBNTotal:FAIL? ).

See FER Measurement Results Specific to Lab Application .

Query

• Range: -30.00 to +42.00 dB, 9.91 E+37

• Resolution: 0.01

Requirements

Lab Application Revision: B.02 and above

Programming Example

 
OUTPUT 714;"FETCh:CFERror:EBNTotal?" 
!Returns the average value of F-FCH Eb/Nt.

Function

Queries the maximum value of the F-FCH Eb/Nt (the energy per bit to total noise) during the FER measurement when FPC mode 000 is enabled on the test set.

See FER Measurement Results Specific to Lab Application .

Query

• Range: -30.00 to +42.00 dB, 9.91 E+37

• Resolution: 0.01

Requirements

Lab Application Revision: B.02 and above

Programming Example

 
OUTPUT 714;"FETCh:CFERror:EBNTotal:MAXimum?" 
!Returns the maximum value of F-FCH Eb/Nt.

Function

Queries the minimum value of the F-FCH Eb/Nt (the energy per bit to total noise) during the FER measurement when FPC mode 000 is enabled on the test set.

Query

• Range: -30.00 to +42.00 dB, 9.91 E+37

• Resolution: 0.01

Requirements

Lab Application Revision: B.02 and above

Programming Example

 
OUTPUT 714;"FETCh:CFERror:EBNTotal:MINimum?" 
!Returns the minimum value of F-FCH Eb/Nt.

Function

Queries the Eb/Nt pass/fail result for the FER measurement when FPC mode 000 is enabled on the test set. If the average Eb/Nt ( FETCh:CFERror:EBNTotal[:AVERage]? ) is no greater than the specified Eb/Nt limit ( SETup:CFERror:EBNTotal[:LIMit] ), '0' will be returned to indicate that the mobile station has passed the Eb/Nt limit for the FER test. Otherwise, '1' will be returned to indicate that the mobile station has failed the Eb/Nt limit for the FER test.

When the test set is not in FPC mode 000, this query returns 'NAN'.

See FER Measurement Results Specific to Lab Application .

Query

Range: 0 (Pass), 1 (Fail), 9.91 E+37 (NAN)

Requirements

Lab Application Revision: B.02 and above

Programming Example

 
OUTPUT 714;"FETCh:CFERror:EBNTotal:FAIL?" 
!Returns the Eb/Nt pass/fail result.

Function

Queries the forward channel frame erasure count.

This measurement result is the number of frames the mobile station was not able to decode.

Query

• Range: 0 to 10,000,000, 9.91 E+37

• Resolution: 1 frame

Programming Example

 
OUTPUT 714;"FETCh:CFERror:ERASures:FORWard?" 
!Returns the number of forward frame erasures.

Function

Queries the reverse channel frame erasure count.

This measurement result is the number of frames the test set could not decode.

In loopback mode, the reverse link should be transmitted at a power level that does not introduce frame errors. Reverse erasures could be caused by poor transmitted signal quality from the mobile station.

Query

• Range: 0 to 10,000,000, 9.91 E+37

• Resolution: 1 frame

Programming Example

 
OUTPUT 714;"FETCh:CFERror:ERASures:REVerse?" 
!Returns the number of reverse channel frame erasures.

Function

Queries the number of frames that were determined by the test set to contain frame errors. The test set performs a bit-by-bit comparison between the transmitted vs. received data to check each frame received in loopback mode. The mobile station either reported these frames as error free or detected errors but thought it had corrected them.

Query

• Range: 0 to 10,000,000, 9.91 E+37

• Resolution: 1 frame

Programming Example

 
OUTPUT 714;"FETCh:CFERror:ERRors?"
