An eye-diagram is basically</p><p style="margin:0;">an infinite persisted overlay of all bits captured by an</p><p style="margin:0;">oscilloscope to show when bits are valid. This provides</p><p style="margin:0;">a composite picture of the overall quality of a system’s</p><p style="margin:0;">physical layer characteristics, which includes amplitude</p><p style="margin:0;">variations, timing uncertainties, and infrequent signal</p><p style="margin:0;">anomalies.</p><p style="margin:0;">Eye-diagram testing can be performed on differential</p><p style="margin:0;">Controller Area Network (CAN) signals using an Agilent</p><p style="margin:0;">3000 X-Series oscilloscope licensed with the DSOX3AUTO</p><p style="margin:0;">trigger and decode option (CAN &amp; LIN), along with the</p><p style="margin:0;">DSOX3MASK mask test option. Various CAN mask files can</p><p style="margin:0;">be downloaded from Agilent’s website at no charge. Save</p><p style="margin:0;">the appropriate CAN eye-diagram mask files (based on baud</p><p style="margin:0;">rate, probing polarity, and network length) to your personal</p><p style="margin:0;">USB memory device. The following CAN mask files are</p><p style="margin:0;">available:</p><p style="margin:0;">Introduction</p><p style="margin:0;">• CAN-diff (H-L) 125kbps-400m.msk</p><p style="margin:0;">• CAN-diff (L-H) 125kbps-400m.msk</p><p style="margin:0;">• CAN-diff (H-L) 250kbps-200m.msk</p><p style="margin:0;">• CAN-diff (L-H) 250kbps-200m.msk</p><p style="margin:0;">• CAN-diff (H-L) 500kbps-80m.msk</p><p style="margin:0;">• CAN-diff (L-H) 500kbps-80m.msk</p><p style="margin:0;">• CAN-diff (H-L) 500kbps-10m.msk</p><p style="margin:0;">• CAN-diff (L-H) 500kbps-10m.msk</p><p style="margin:0;">• CAN-diff (H-L) 800kbps-40m.msk</p><p style="margin:0;">• CAN-diff (L-H) 800kbps-40m.msk</p><p style="margin:0;">• CAN-diff (H-L) 1000kbps-25m.msk</p><p style="margin:0;">• CAN-diff (L-H) 1000kbps-25m.msk</p><p style="margin:0;">Please see attached file for full details.</p> <div class="migration-injected-attachments"><div style="font-weight:bold;margin:15px 0 5px 0;">Attachments:</div><div></div><table style="border:0;"><tbody><tr><td width="160"><span class="_se_attachment" id="attid_https://www.element14.com/community/api/core/v3/attachments/99517"><a href="https://community.element14.com/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-21/5991_2D00_0484EN.pdf">community.element14.com/.../5991_2D00_0484EN.pdf</a></span></td><td><span style="font-size:80%;">5991-0484EN.pdf</span></td></tr></tbody></table></div><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: 3000, mask, series, testing, eye, application, diagram, oscilloscope, for, notes, can, dsox, agilent</div>
