Programming a Loopback Bit Error Ratio Measurement

Programming Example

10 OUTPUT 714;"SETup:WBERror:CONTinuous Off"!Set the loopback BER
20
30 OUTPUT 714;"SETup:WBERror:TIMeout 10S"!Set a timeout value of 10 secondS
40
50 OUTPUT 714;"SETup:WBERror:COUNt 12200"!Set the bits to test to 12200.
60 OUTPUT 714;"INITiate:WBERror"!Start the measurement.
70 OUTPUT 714;"FETCh:WBERror?"!Query the returned integrity indicator and the
80
90 ENTER 714;Integrity,Ber_percent,Bit_errors,Bits_tested !Enter the returned
100
110 IF Integrity<>0 THEN !Integrity <> 0 indicates an
120 PRINT "Measurement problem; check for signal level over/under range condition."
130 ELSE
140 END IF
150 END

Returned Values

• Integrity stores the returned integrity indicator value (see
measurement with no errors.
• Ber_percent, Bit_errors, and Bits_tested store the returned values for the bit error ratio (in %), the
number of bit errors measured, and the number of bits tested, respectively.
