Part Number: DP83867IR
I am trying to probe TX_CTL and RX_CTL signals of the gigabit PHY DP83867. I use a 100MHz (10MOhm, 11pF front end) Mixed signal oscilloscope (Agilent MSO6014A) with a 500MHz, 11pF CAT I, II probe (Keysight N2834A). I see some overshoot on the rising and falling edges of the signal and I am not sure if this is due to probing or the signal itself has the overshoot.
How do I make sure the probing (parasitics in probe and scope) doesn’t affect the signal? What is the recommended setup to measure such fast transitioning signals?
