FETCh:BLERror:CRC?

Function

 GSM TA

This command is not applicable to GSM.

GPRS TA

This query returns the CRC (Frame Check Sequence) Error Count found during the last BLER measurement. Each block that fails its CRC will cause the CRC Error Count result to increment.

The CRC Error Count is only applicable to loopback BLER measurements. NAN will always be returned for polling BLER measurements. (Refer to BLER measurement method usage .)

The CRC Error Count affects the BLER measurement results differently depending on the BLER Bad Block Handling setting. For more information on the BLER Bad Block Handling setting see SETup:BLERror:BBLocks .
