Key features of the LECROY SDA 7Zi-A serial data analyzer from the United States:

Powerful SDA II analysis package

Serial data analysis can unleash powerful power, helping you understand and characterize your design, validation rules, and determine why a slave or host fails in consistency testing.

And how do you determine a device consistency failure? For identifying the root cause of serial data consistency failure, the Lico SDA II serial data debugging software is the most powerful and feature rich solution. SDA II can give you confidence and ensure that you receive the correct functionality.

SDA 7Zi-A is the only oscilloscope that can help you confirm issues and ensure that your project can proceed as planned.

Automatic consistency testing

The QualiPHY consistency testing software package can be installed using an application to perform consistency testing on various serial data standards. The rapid automatic testing operation, instruction instructions, and connection diagram simplify the process. When 'stop when failure' is enabled for debugging, a complete test report can be provided at the same time.

Whether it's debugging eye diagrams or other consistency failure tests, the SDA 7Zi-A series provides corresponding tools to quickly identify the problem points in your design. More advanced features such as 8b/10b decoding, template violation localization, ISI Plot, and balancing can be easily found. SDA 7Zi-A has not yet provided automatic adjustment functions for cable characteristics and cable removal, in order to obtain the true rise time and amplitude of the signal during measurement. SDA uses flexible and consistent mathematical operations in mathematical analysis, which is highly effective for understanding the design approach in consistency failure events.

SDA II - Advanced Tool for Analyzing Isolation

Flowchart User Interface

The eye diagram and jitter analysis in the LECROY SDA 7Zi-A serial data analyzer from the United States use a simple interactive flowchart user interface to intuitively guide users through the setup of eye diagram testing and jitter testing, or both.

Serial trigger

The LECROY SDA 7Zi-A serial data analyzer series from the United States comes standard with an 80 bit sample trigger function. SDA 760Zi and SDA 740Zi have high-speed mode triggering options (with a maximum sampling rate of 2.7 Gb/s); The SDA 735Zi and SDA 725Zi are equipped with a mode trigger option with a sampling rate of up to 1.25 Gb/s. Both mode triggers provide a recovery clock and data output at the oscilloscope front-end.

8b/10b decoding

The 8b/10b serial decoding option of Lico, combined with powerful search performance, makes it possible to search for user-defined symbol sequences in captured waveforms. At the same time, multi language decoding can be performed simultaneously on up to 4 capture channels.

balanced

Balancing eliminates the impact of using a balancing system. Users can observe the waveform eye diagram as if equipped with a balanced receiver.

ISI Plot

ISI plot can display the impact of inherent data jitter on eye plots, such as the effect of 3 to 10 bits on the second to last bit on a certain data length. Using Plot to measure inherent data jitter does not require repeated bit patterns.

Jitter Spectrum

The jitter spectrum plot can observe any periodic jitter

Peak annotation directly displays the frequency on the spectrogram

The spectrum plot of the LECROY SDA 7Zi-A serial data analyzer from the United States can observe data correlation jitter, allowing for a deeper understanding of it

Shake trend

The time-domain image of jitter displays the momentary events of jitter, which may often be overlooked when only looking at the histogram.

The shaking trend clearly displays any non-stationary shaking behavior

Histogram&Bathtub Diagram

The measured jitter histogram clearly displays the impact of any abnormal jitter, such as bimodal or non Gaussian tails. By simply observing the jitter decomposition (Rj, Dj), the original data image shows jitter behavior that can be discarded.

These unprocessed displays provide highly reliable jitter decomposition and bathtub curve accuracy

Eye diagram displaying template violation relative to position

Eye diagram measurement can be performed on up to 8 million consecutive bits, ensuring that both instantaneous jitter and noise can be captured

Continuous bit eye diagram analysis can perform waveform measurements on independent bit positions, i.e. separating consistency templates (violation localization)

Fastest UI accumulation and lowest measurement jitter (typical value is 1ps rms)

Cable embedding

Expensive high-performance cables can also have adverse effects on measurements and increase design costs. Cable loss and low rise time can cause inter symbol interference on the measurement system rather than in the design. The cable removal function offsets this adverse effect, resulting in more accurate measurements.

Advanced debugging and jitter analysis of SDA II eye diagram

The X-Stream II technology of the LECROY SDA 7Zi-A serial data analyzer from the United States has achieved unprecedented speed in creating eye maps. The SDA 7Zi-A, equipped with a 15.3-inch high-resolution display and flexible landscape display technology, provides a more detailed and in-depth observation of eye images than ever before. New features, such as IsoBER, enhance insight into traditional non quantitative eye diagram windowing.

In addition, correctly distinguishing between random and fixed jitter in serial data signals is an important part of reducing overall jitter. For example, correctly identifying the frequency of periodic jitter is a typical universal method for determining the source of jitter. SDA 7Zi-A is the only analyzer that fully integrates jitter measurement into oscilloscope software, greatly improving the accuracy of jitter measurement.

Binocular mode

Observing changing and non changing eye diagrams can analyze the de emphasis of serial data waveforms. In addition, the binocular shutter can create two separate eye maps (e.g. read/write) based on a separate signal input.

Template violation positioning

Template failure can be confirmed by comparing the data appearing at any point with the colored dots generated by the intersection of the template. Users can call the measured bit stream waveform stored at a certain point during the initial failure. The measured bit sequence can also identify any ISI issues. You can immediately jump to the next violation point or other saved modes.

IsoBER

Template testing is not always the best method for detecting signal crosstalk, as it lacks quantitative analysis of vertical noise and jitter. The unique IsoBER analysis tool from Lico can extrapolate eye diagram data and display error rate lines directly on the eye diagram, helping engineers quickly determine the minimum opening of the eye diagram and verifying crosstalk by analyzing the closure of the vertical eye diagram. Standard eye diagram technology cannot achieve these measurements.

More confidence in jitter isolation

Simplify jitter decomposition

The jitter source can be divided into intrinsic and random jitter, which is an important difference when calculating total jitter (TJ). Sometimes crosstalk or other types of inherent jitter may disguise as random jitter, leading to erroneous calculations.

The built-in SDA II jitter analysis tool from Lico provides two decomposition algorithms to handle this situation, giving users more confidence in their measurement results. Jitter decomposition simultaneously calculates two algorithms and prompts the user when there is a deviation in the measurement results to ensure that the displayed jitter value is correct.

Intuitive jitter decomposition display

The SDA II from Lico provides an intuitive visualization of jitter decomposition charts, allowing for quick insight into the root cause of problems.

In order to better understand inherent jitter and its sources, SDA II provides the following tools:

The spectral characteristics of periodic jitter can identify the source of the most significant periodic jitter (Pj).

2.2 ISI Plot isolates the bits that contribute the most intersymbol interference (ISI).

The histogram of 3.3 DDj provides in-depth insights into the distribution of data correlation jitter (DDj).

Set warning indicators

Green/yellow/red warning indicators are set to remind users whether they need to pay attention here. For example, if the signal input by the user is a clock but no clock signal type has been selected for it, a yellow indicator will be displayed to alert the user of a conflicting situation in the settings.
