I am not sure if I need to be DC coupled. My assumption is that it will be needed, because the attenuator needs a dc voltage to control the amount of attenuation that is applied to the RF. I have...

Hi Naveen, Your SPI mode may be incorrect. It looks like you have set the SPI polarity to low, and phase to first edge. This DAC captures data on the falling edge. Try swapping the phase to the second...
