Programming a Waveform Quality Measurement

Programming Example

10 OUTPUT 714;"SETup:WWQuality:CONTinuous Off"
20
30 OUTPUT 714;"SETup:WWQuality:TIMeout 1S"!Set a timeout value of 1 second
40
50 OUTPUT 714;"SETup:WWQuality:COUNt 5"
60
70 OUTPUT 714;"SETup:WWQuality:TSLot 11" !Set the measurement to
80
90 OUTPUT 714;"INITiate:WWQuality" !Start the waveform quality measurement.
100 OUTPUT 714;"FETCh:WWQuality?"
110
120 ENTER 714;Integrity,Evm,Freq_err,Orig_off,Phs_err,Mag_err !Enter the
130 !returned integrity indicator and measurement values into variables.
140 IF Integrity=0 THEN !See if the integrity value = 0 (valid measurement).
150 ELSE
160 PRINT "INTEGRITY";Integrity
170 PRINT "Measurement problem; check for signal level over/under range condition."
180 END IF
190 END

Returned Values

• Integrity stores the returned integrity indicator value (see
measurement with no errors.
• Evm returns the maximum error vector magnitude result.
• Freq_err returns the worst case frequency error result.
• Orig_off returns the maximum origin offset result.
• Phs_err returns the maximum phase error result.
• Mag_err returns the maximum magnitude error result.
!Set the waveform quality
!measurement to single trigger mode.
!in case the measurement cannot be made.
!Set multi-measurements to 5 and
!enable multi-measurements.
!measure waveform quality during timeslot 11.
!Query the integrity indicator and all
!results for the waveform quality measurement.
