4.1 Single-Channel RF Mode 2 (2nd Nyquist Zone)

In the DAC GUI, click on the DAC12DL3200 → DACA tab. For single DAC operation in the 2nd Nyquist zone, in the DACA_output mode box, select RF mode. With the DAC sampling at 6.4 GHz, and with an input tone at 2.6 GHz, the image will be located at 3.8 GHz in the 2nd Nyquist.
