Stratix IV GX development board and DAQ card

I have the Stratix IV DEV board, which has 2 HSMC and PCI express interface. Now I am searching for a card which

1.can do the ad/da convert for low frequency signals(several hundreds hz to 6k hz)

2.can input the digital signal to fpga board and convert the digial output from fpga board into analog signal

3.What's more, the card should have at least 2 input output channels.

Since all of the daughter cards I can find can only handle high frequency signals:confused:, would someone please give me any suggestion about the hardware choice ?

Many many thanks!

Juan

    there seems to be a hole in the market for HSMC cards with DC coupled ADC/DAC.

    the only thing i can recommend is buying one of the AC coupled ADC/DAC boards and modulate your input signal to the passband of the ADC circuit. or build your own HSMC card with your own ADCs.
