FETCh:BERRor[:ALL]?

Function

 GSM TA

Queries the bit error measurement. Query returns integrity indicator, bits tested, bit error ratio, and bit error count. (A similar query, FETCh:BERRor:FULL? , returns the same results but for all bit types simultaneously.) See Bit Error Measurement .

FETCh:BERRor:BITS?

Function

 GSM TA

Queries the number of bits actually tested. This query only returns the result of the bit type set using the SETup:BERRor[:TYPE] command.

The number of bits actually tested will exceed the number requested because the test set rounds up the number requested to the nearest number that results in an integral number of speech frames. One speech frame is 132 bits. The test set measures complete a speech frame and it is queried for bits. See Bit Error Measurement

FETCh:BERRor:COUNt:CRC?

Function

GSM TA

Queries the number of bad cyclic redundancy checks (CRCs) for a non-residual measurement type, loopback type B test. See Bit Error Measurement

The mobile station re-transmits the CRC it received from the test set on the uplink.

A bad CRC occurs when the CRC transmitted by the test set does not match what is received back from the mobile station.

The manual user must set the measurement unit to count.

FETCh:BERRor:DELay?

Function

GSM TA

Queries the delay (in speech frames) that the test set used during the last bit error measurement to correlate uplink information bits with downlink information bits.

This value is displayed in the Loopback Delay field.

This value can be determined automatically, or manually set by the user. See SETup:BERRor:MANual:DELay and SETup:BERRor:LDControl:AUTO .

Refer also to the Bit Error Measurement for a description of loopback delay and how it is used in the bit error measurement.
