How to measure signal quality of high speed transmission line

challenger002
Intellectual 690 points

I want to measure signal quality of high speed transmission line.

I use sRIO, AIF2, PCIe on C6670 DSP.

Which measurement equipments should I use?
In addition, is there the example (manufacturer, model number, etc...)?

Can you give me DSP software for the measurement?
Or is there the information to make DSP software for the measurement?

Thank you.

    There are various companies such as Lecroy, National Semiconductor, Techtronix, etc. that make measurement equipment for various high speed differential signalling IOs such as you've mentioned.  It would be better for you too look into them and what they offer as it really depends one what you're trying to look for (protocol, signal integrity, eye diagram, etc.)  You may want to look into a mainframe/chassis one that has slots for cards to be added for testing of the various IOs if you're planning on testing multiple IOs.

    Most will require you to program the DSP to provide specific patterns.

    Best Regards,

    Thank you for an answer.

    Can I see which measurement equipment was used with an evaluation board of C667x or other boards of C667x which you know?
    In addition, can I get a test pattern program of C667x DSP which was used with these boards?

    Thank you.
