Hi all, Marcus, Thanks for the answer, it was really useful. Now, I am trying to generate the 10Mhz signal using a vector signal generator, but the signal is nor really pure because the signal generator bandwidth is only 60MHz. Also, the Vpp of the signal is 1.4 V, is it correct?
If someone can see the signal (in attached) and tell me if I can use it as an external clock, it will be really helpful. Best regards, Alejandro 2018-04-05 16:34 GMT+02:00 Marcus D.
