AD-FMCDAQ2-EBZ and kc705 DAC problem

hi,

 

we are testing AD-FMCDAQ2-EBZ with kc705 board.

 

We used desing files kc705_fmcdaq2_2015_R1_PRE.zip with IIO Oscilloscope for Windows - v0.2-2015_R1 and windows 8. Static IP address for host and target.


the board works correctly except for the DAC configuration, in particular we noticed that in the IIO configuration changing DAC_2 parameters doesn't affect the output and the DAC_1 parameters affects both DAC output on board,  for example connecting Out1->In1 and Out2->In2 and setting on DAC_1 a 40 MHz sinewave and on DAC_2 a 2 MHz sinewave both ADC_1 and ADC_2 shows the 40 MHz. Turning off DAC_1 we see no signal on both ADCs. Connecting only Out1->In1 and setting on DAC_1 a 40 MHz sinewave we see on ADC_1 the correct sampled signal and no signal on ADC_2.

 

can you verifiy this? Thank you and best regards,

 

Maurice Saccani
