Waveforms
Notes:
1. Circled figures represent the measuring points in the circuit diagram.
2. Reference voltage VC: 1.65V <
· VC >
3. Premastered MD, Make measurements using the MMD110.
Nonetheless, waveforms indicated as “Recordable MD” should be
measured using the MMD212.
4. Use TMD325W as the Defect MD.
