Unable to send a number with DAC and receive a number with ADC in a deterministic manner

Hi team,

If using DAC sending a pulse to ADC with a loopback setup, do you know how to fix the number? For example, if choose pulse_gain as 500, I can get readout amplitude 3.5. But is there a way to deterministically control the amplitude, e.g. send 3.5 and get 3.5. Thanks!

No, you would need to calibrate that yourself for your specific frequency, choice of baluns, and cable losses.
