| FEATURES |
 |
| ■ |
Wow flutter measurements possible in accordance with different standards for RMS, NAB at 3kHz and for IEC (DIN/CCIR) at 3.15kHz. |
| ■ |
Wide wow flutter range, 0.001% to 3%, for accurate measurements for all classes of recording/playback equipment. |
| ■ |
Measurements can be made under weighted and unweighted conditions; in addition, wow and flutter can be separately determined. |
| ■ |
At IEC(DIN/CCIR) measurements, a sigma memory for three modes, 1σ, 2σ, and 3σ, enables readings at the hold condition of the meter. |
| ■ |
FIN (Frequency Intermodulation) measurements in accordance with DIN45411 are possible. |
