Hi, I am designing a pcb board and I wanted to know if the AIN on the labjack U6 can read AC Voltages. I previously did i streaming and over sampling, but for this application the frequency I need to measure is 20MHz making it impossible to measure the frequency oversampling. I on the datasheet it doesn't say that it can't but it doesn't say that can. Thanks in advance. Marco.

The fastest stream rate is 50k, so the fastest waveform you could acquire would be 25 kHz, but that is only the Nyquist minimum so you would not see much. If you just want to measure frequency, you can use a Counter, but even that is only specified up to 8MHz on the U6.
