On a DVD-RAM, the jitter analysis must be performed separately for the header and data sections. In addition, since a DVD-RAM is of ZCLV type, automatic scaling is needed in order to handle the clock changes. The TA520 has the following functions to meet these requirements :

• Measurement range spans over multiple tracks (block sampling function).
• Limit the range of the measurement angle (arming gate function).
• Separately measure the header and data sections (inhibit function).
• Automatic scaling for handling clock changes (auto window function).
