AD9854 with ATMEGA32 and USB

G'day Forum,

Please go easy on me as I am a beginner

Here goes, another impulse Ebay buy finally arrived. 

http://www.ebay.com.au/itm/280993325242

Really I want to use it to output waves that I can watch on my oscilliscope.

Now I can't figure out how to use it without the little control app.  The "AD9854 Control_Softwear" I am using now (AD9854_Software.exe from the souce code\For_VB directory that I got from the ebay seller) allows me to set the following:

Frequency1

Frequency2

Delta Frequency

Ramp Rate Clock

Reference Clock

Output Amplitude checkbox with I and Q sliders

Triangle checkbox

Multiplication Frequency dropdown with X0-X10 options

Work Mode dropdown with Single Tone, FSK, Ramped FSK, Chirp and BPSK

I have a bunch of questions, please help: 

Does anyone have the pinouts for JP2, basically it's 6 pins? 

What does the VR1 pot set, do I need to touch it?

Why does it have 6 SMA ports, I have tried E1 and E2 and both have a default freq of 1.000mhz and a prd of 1.000us what do e3 thru e6 do?

The fourth image here: http://item.taobao.com/item.htm?id=9044735744 shows an updated software with the following settings that I don't have, I think this guy Zhang Lihua 88 might be the designer of the board: 

Looks like Wave Set, this could be a crucial one as I would like to get a square wave!

CLR ACC1

CLR ACC2

Function

Time value

Anybody got this updated software or are familiar enough with these boards to help me out?

Thanks for looking.

  • Hi Richard,

    I am not quite sure if someone in ADI has been able to use the same board that you were able to purchase. If someone has, then we can definitely help you out. However, even if the DDS is AD9854, the board is not released by Analog Devices, Inc so we cannot support about its software and also its hardware since we do not have a copy of its schematic.

    If it helps, we have an evaluation software of AD9854 in which you can look into and might find some similar functionality with the board you are using.

    Here is the link for the software installers and schematic: AD9854 Software and Schematic.

    Hope this helps.

    Best Regards,

    Sitti

  • Thanks Sitti, of course I do not expect hardware or software support

    I am interested in the capabilities, it has two DACs, does that mean it can output two distinct waves?

    Does anybody reading this have a board like this?

    Thanks.

  • Hi Richard,

    The two DACs are for the I and Q output signal. Thus, the DDS can output two waves 90 degrees out-of-phase, that is the inphase signal (I signal) and the quadrature signal (Q signal).

    I will ask DSB if he know someone who is familiar with this board. And I'll get back to you as soon as possible.

    Best Regards,

    Sittie

  • Hi Richard,

    I would like to follow-up. I asked DSB and he is also not familiar with this particular board.

    Thanks.
