FETCh:WBERror

Function

Queries the Loopback BER Measurement Results .

[:ALL] returns measurement results in the following order: integrity, bit error ratio, bit error count, bits tested.

Instead of querying [:ALL] results, you may query an individual result using the appropriate keyword (for example, FETCh:WBERror:RATio? returns the bit error ratio result only).

Range

• Integrity: see Integrity Indicator .
• Bit Error Ratio: 0 to 99.0000%, 9.91 E+37
• Bit Error Count: 0 to 999999999, 9.91 E+37
• Bits Tested: 0 to 999999999, 9.91 E+37

Resolution

• Integrity: 1
• Bit Error Ratio: 0.0001%
• Bit Error Count: 1
• Bits Tested: 1

Requirements

Test or Lab Application Revision: A.01 and above
