Hello,
I've purchased USB-205 daq, which I plan to use for acquiring IQ data. I'd like to sample the signals synchronously, applying external ADC clock and trigger.
I tried to capture some data using DAQami (eval version).
It appeared, however, that the SW doesn't provide an option for using the clock provided on the pacer input terminal AICKI .
Could you advise, please, whether my observation is correct and whether options for circumventing that are available? (In the application, I plan to use a python script for capturing and processing the IQ data and hope, that that it won't be an issue.)
I have also a question concerning the synchronicity of sampling when using 2 analog inputs.
The attached screenshot shows one signal, sampled simultaneously by AI1 and AI0. It appears, that the signal on AI1 is delayed with 1 ADC clock cycle (SR=250kHz). I wonder whether the delay is determined by device's HW design, or can be prevented by applying a proper configuration.
Thank you in advance.
Regards,
Atanas
