I use two different tile adc and dac to transmit real part signal and imaginary signal.
The rf data converter is in bypass mode.
the result is following:
transmit:

settings:
is it normal the sinusoidal with different amplitude?
thanks!
Via which code are you obtaining your graphs?

Hi,
I used the matlab library and i don’t think it’s the problem.
I use the ILA to check the ADC values of two tiles, and they are significantly different.
import matplotlib.pyplot as plt
x = np.array(range(0, points_rx))
#plt.subplot(211)
#plt.plot(x, data_tx_ch2_i)
#plt.plot(x, data_tx_ch2_q)
#plt.subplot(212)
plt.plot(x, data_rx_i[:,14],label=‘real part’)
plt.plot(x, data_rx_q[:,14],label=‘imaginary part’)
plt.legend(loc=‘upper right’)
plt.show()
