Eye Aperture isn't taking place at values of my interest

ventati1990 over 4 years ago

Hi , In the image attached, its a combination of 8 eye diagrams. I am using eye aperture calc function for automatic generation of the mask. My desired vref is 660mv, VHiDC = 785mv (verf+125mv) & VHiAC = 810mv(Vref+150mv). Eye aperture fails to evaluate at these values because eye opening maximum is 741mv where V1 & H1 intersects, where V2 &H1 intersects it can evaluate. But it evaluate only at V1 crossing not V2. Is there any way to evaluate and create mask connecting between 810 mv & 785mv ?

If i try have custom mask of my own, tool let me select only one mask at a time. Is there any way to apply custom mask to all 8 eye diagrams in one go?

I would suggest you contact customer support for this. Others may be able to help, but I don't have enough spare time today (I answer here in spare minutes throughout the day) to set up an example and test this out to fully check what you're saying...

Hi Andrew, Thank you for your time. I have access to tool only but not to customer support. As it seems no one replied, if you can provide the solution after few days is also ok to me.
