We are getting a strange spectrum when trying to generate a single tone:
Settings: CGEN 200MHz.
DIQ1 BB interface sending single tone at full scale (12 bits)
CGEN set to 200MHz. Default TSG is TSPclk/8 (TSPclk = CGEN by default) so single tone should be at 200MHz/8 = 25MHz but in this case it is at 12.5MHz.
Output set to maximum gain.
When sending a signal from FPGA:
Modifying txpad gain to -30dB
