Data transmitted to the TA720 through an Ethernet connection can be saved to the PC card or shared over a network. In addition, measurement conditions can be set and controls such as starting and stopping measurements can be entered over the network when an Ethernet connection is used.
Dual measurement function can be used to simultaneously measure an optical diskÂ¿s data-data jitter and data-clock jitter. In the past, it was necessary to do these measurements separately, so there was a need for steps such as synchronization using an index signal from a spindle motor as a measurement-start control signal. With the TA720, however, these two measurements can be done simultaneously, so data-data jitter and data-clock jitter from the same measurement area are obtained at the same time.
Function extracts data corresponding to specified conditions, such as jitter for each space length immediately following a 3T mark, and jitter in each space length between one 3T mark and another. This data can be used to analyze the effects of the code on jitter. The inter-symbol interference analysis function is useful for evaluating recording strategies, such as recording power control and phase control, and recording waveforms.
