**Part Number:**DATACONVERTERPRO-SW

**Other Parts Discussed in Thread:**ADC3444EVM, ADC3443EVM

Dear Ti,

I am trying to capture signals with a TSW1400EVM and ADC3444EVM. I have and external clock and connected the ADC3444EVM to a function generator to test. I set the function generator to output a sin wave with 100kHz (or any other frequency) and when I read the data I just captured the FFT has one peak at 100kHz like expected, however, when I try to read the time domain there is no signal, only zero volts and a little bit of noise. I am confused because my system seams to work in the frequency domain but not the time domain despite the ADC sampling in the time domain. Does anybody have an idea of what is going on or how to get my system to work?

Your help is greatly appreciated.
