generate and acquire signals

I write to give information about the project that I am doing with a embedded controller PXIE 8840 and its module PXIE 6356. Initially we want check the speed of capture and writing of a similar signal between a frequency range from 100HZ to 500KHZ. This signal is read by one of the analog entries and immediately without any modification sent or written for one the analogous outputs. Our goal is that this signal can enter at different frequencies and can be reproduced with the same characteristics (only slightly delayed by ADC and DAC times), which is successful for a cutoff frequency according to the parameters set in the block, but for a range of frequencies the signal is not reflected in the outputs, which has a continuous 0V output. Our concern is how to configure the block so that it allows us to capture the entire frequency range of the input signal or if there is another way to do it differently than using the DAQ Assistant in Labview. Attached with this mail sent a project of how we are using the DAQ and some images of the configuration used

Tell me if I understood correctly. You want to acquire a signal and send out again on the same module without any modification to the signal ?

yes is correctly, i just need to generate a signal with frequency 100 hz from to 500 khz but i need to oscilate that frequency in the range that I want , and adquiere that signal with the same frequency

Can you please first check the examples from LabVIEW, you just need to click on help - Find Examples and Analog Output. Check the picture attached. You need to avoid using express VIs.Analog Output.PNG

i did the examples, but when i modificated that program does not function like i want

Can you share the VI created by you (without express VIs)
