I am trying to measure the jitter contributed by a card in my system. The clock input on the card is driven by an Anritsu BERT generator. My card under test sends the input clock to a simple two stage buffer without any PLL's. I can measure the jitter on the clock out of the Anritsu and I can measure the jitter on the clock out port on my card with an Agilent 86100 scope. The question is: is it a simple subtraction process, (jitter out - jitter in = jitter contributed by my card) since the jitter has both deterministic and random components?
