Measure eye-diagram using a scope
Measure eye-diagram using a scope
(OP)
Hi,
I would like to measure the eye-diagram of the DDR's clock. What do the oscilloscope probe connections look like in order to display the eye-diagram?
Also, the DDR clock is 133MHz, what's the required oscilloscope bandwidth? If I use a 2pF FET probe to probe the clock, will it be OK?
Thank you in advance!
James

RE: Measure eye-diagram using a scope
As for the others, that depends on what you're driving the scope probe with, does it not? What are the specifications of the driver chip?
