Key features of the LECROY DDA 7Zi-A disk drive analyzer from the United States:

A complete solution for disk drive analysis;

2. Highest performance;

The built-in tools of the LECROY DDA 7Zi-A disk drive analyzer from the United States can assist data storage engineers in accelerating the speed of new product launches to the market, and speeding up the understanding and failure analysis of existing drives. Lico continues the tradition of the DDA 7Zi-A series by equipping it with a powerful disk drive analysis toolbox. Quickly and comprehensively capture, observe, and analyze high-speed and complex driver signal waveforms.

Data storage applications are very sensitive to memory, such as capturing data from multiple sectors or a complete track, which is of great significance for solving design failures or characterizing media.

The X-Stream II architecture can quickly and accurately measure and analyze disk drive signals. By using option L, the storage can be expanded to 128 Mpts/Ch (2 channels with 256 Mpts/Ch). DDA 760Zi and DDA 735Zi can both conveniently choose between 50 Ω or 1M Ω inputs. Two channels are equipped with 20 Mpts waveform memory and a sampling rate of 40 GS/s, which means that multiple drive sectors can be sampled simultaneously.

Flexibility in long-term storage and problem finding

Get a head signal up to 6GHz and then use the quick zoom button on the front panel to zoom in and out. DDA will automatically copy and expand the driver signal. Simply scroll horizontally and vertically to check any sector. Multiple scaling allows you to observe the head signal from 8 different regions; Each scale uses a different color. Disk drive parameters allow you to qualitatively analyze changes in pulse width or signal-to-noise ratio within a certain area. Failure analysis engineers can store and recall important waveforms and panel settings to compare problematic drivers with normal drivers. The analog-to-digital converter operates at speeds of up to 40 GS/s to ensure sufficient sensitivity for measuring today's high-speed read channels. With each DDA, you can run your custom script and use filters that match your channel and medium to observe the captured signals.

User defined scripts can be created using MATLAB, Visual Basic, Excel, or other formats.

Special triggering and sequence performance

The disk trigger of the LECROY DDA 7Zi-A disk drive analyzer from the United States allows you to set a series of events for the signal and activate the trigger. For example, verifying the signal on the index signal and capturing information of all sectors on the track. With the increase of memory on DDA, more sectors can be captured at event resolutions of up to 50 microseconds per sample. The DDA 7Zi-A analyzer can collect data from up to 15000 sectors. Another additional feature, stream sequencing, using DDA's X-Stream II and fast hardware architecture, can store up to 300000 pieces of data into memory; And it adopts a high-speed triggering frequency.

Natural graphical interface

Pressing the DDA menu will take you directly to the disk drive analyzer function. Similar controls on the front panel, coupled with a natural context sensitive graphical user interface, can quickly respond to your commands. This feature is exactly what you want.
