Re: I am getting time lag between NI 4452 and NI 6602

Daniel, What you are seeing is expected and you were almost exactly right with your formula. The DSA boards use a digital filter to remove frequency components above Nyquist. This introduces what we call Filter Signal Delay. This spec for the 4452 is 42 samples, so the formula is actually: (ti

Re: I am getting time lag between NI 4452 and NI 6602

Hello Daniel, I have a couple of questions regarding this problem. 1) What kind of signal are you using to trigger the counter and the analog signal (Is this the pulse train that you referred to?) 2) Do you have the DSA device set as the master? The DSA device must be set as the master for th

I am getting time lag between NI 4452 and NI 6602

Hi. I am using a NI4452 DSA device to aquire analog signals and I am using a NI6602 counter/timer device to determine the time ocurrence of a pulse train related to the analog signals. I am also using an RTSI cable to synchronize the analog input start and the counter start. I wired the pulse train
