| FEATURES |
 |
| ■ |
Wide measurable wow flutter range 0.0015% for testing the highest grade to general-purpose recording and playback equipment. |
| ■ |
Accurate measurement under different standards: Effective value for RMS, average value for NAB, and peak-value for IEC (DIN, CCIR). |
| ■ |
Wow flutter measurements under standard weighted and specified unweighted conditions; in addition, wow and flutter values can be separately determined. |
