Yokogawa-TIME INTERVAL ANALYZERS (Model:TA720 )

The TA720 Time Interval Analyzer has larger memory capacity and is faster than the highly regarded TA520 and TA320. It has a maximum sampling rate of 80 MS/s, and maximum memory capacity of 1024 k samples (in Time stamp mode). In addition, the TA720 has a variety of completely new functions, such as a dual measurement function, inter-symbol interference analysis function, and an optional Ethernet and PC card interface. This time interval analyzer is the ideal analysis tool for jitter analysis of high-speed optical disk signals and recording characteristic evaluations.

Highlights of this Time Interval Analyzer, include:

Continuous measurement at up to 80 MS/s

• Maximum Continuous Sampling Rate 80 MS/s
• Dual Measurement Function
• Inter-Symbol Interference Analysis Function, Built-in Printer, and GP-IB Interface are all standard
• Ethernet and PC Card Interface (optional)

High-Speed Continuous Measurement at up to 80 MS/s

• The TA720 can continuously measure signals as fast as eight times DVD speed. It continuously measures high-speed signals from sources such as fast-rotating CDs and DVDs, and next-generation optical disks without dropping measurements. This makes accurate jitter analysis possible.

Dual Measurement Function

• This function enables two measurements to be done simultaneously. The available measurement combinations are Period A & Period B, Period A & A-to-B time interval, Pulse A & Pulse B, and Pulse A & A-to-B time interval. During optical disk jitter measurement, for example, it is possible to perform two types of jitter measurements (data-data jitter and data-clock jitter).

Inter-Symbol Interference Analysis Function

•  With this function, it is possible to extract and analyze data corresponding to set code conditions (such as all T spaces between 3T marks). The distribution of the extracted data and related statistics can also be displayed and compared against all of the data at the same time. When combined with the dual measurement function, the inter-symbol interference analysis function enables even faster jitter analysis through techniques such as extracting data-clock data using pulse width as a condition.

Ethernet and PC Card Interface (optional)

•  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.
