I am currenly doing an evalaution for the AD9833. Could I have a copy of the Labview code for the AD9833 evaluation board?
I can provide a copy of the code but this is with a simple condition, no questions.
Mainly bc we are not providing support for the software.
if you agree, I can send to you.
Thanks a lot. I agree on the conditions. Appreciate it.
Thanks a lot Miguel
Thanks, this looks very helpful. Is there LabVIEW code for other DDS chips? Specifically, anything for the AD9854? Is there a good way to determine from your website which DDS chips have associated LV code and which don't? I agree to your conditions mentioned above as well... Thanks.
Evaluation software and source code can usually be found by following the "Evaluation Boards & Kits" links on a product page. If what you need is not there then just ask here on the forums or call/e-mail the ADI tech support for your region.
I do see the AD9854 evaluation software source code available on our website, but the program is not in Labview. Looking at the file extensions I suspect it is Visual Basic. Miguel may still have something in Labview, though.
Thanks, Kevin. With this in mind, I purchased the AD9834, its evaluation board, and the evaluation microcontroller, as the associated software appears to be LabVIEW. Could you please post or e-mail me the LabVIEW .vi files for this board/eval kit?
Are you looking for the AD9834 or the AD9854? For the AD9854 I'd have to talk to DSB, not Miguel.
If you have any LabVIEW code for the AD9854, I'd love to see it. We have both the '34 and '54 with their evaluation kits. Thanks for the '34 LabVIEW code!
I asked with DSB and we do not have labview code for the AD9854.
Okay, thanks for looking into that. We'll focus on the AD9834, then. The .zip file from musach is a very helpful starting point but there are a few missing files (new sdp.vi, SDP_Blackfin_Base.ldr, SDPDriversNET.exe, DAC.ico, UG-266.pdf). Could you send those along as well? The main VI that you sent in the first attachment won't work without some of those. Thanks again.
Looks like I have all of these files now that I have the disk that comes with the AD9834 evaluation kit. Thanks for everyone's help!
Hello, I am also trying to evaluate the AD9833 however, I am using the EVAL-SDP-CB1Z evaluation board. The idea was to perfrom a quick evaluation, thus far I am not to impressed. I have followed the steps in the User Guide UG-272 and the boards appear to be recognized by the software when connected. When I run the evaluation software and key in a test frequency of 1.7MHx, then hit 'Enter', I would expect that I can find a measurable waveform generated on the AD9833. The user guide tells me that I should find a waveform on IOUT and IUOT2 on the eval board, but no such test points exist. Probing the few testpoints on the board, all ll I can find is a 25MHz (MCLK?) signal at VOUT2. I have verified that the jumpers are set according to the table in the user guide, aside from this the user guide is, quite frankly, useless. Moreover, I do not see a way to generate a square wave from within the interface, just a sine or ramp. Is this possible from within the evaluation environment? Please convince me that this product is still worth cosidering for my project.
You are right, this part has not Iout has includes internally the load resistance....
The correct pin is Vout.
You can generate a square signal using the Sign bit output option.
Before trying to generate any waveform, have you reset the part?
You can improve your sine wave signal connecting an small cap in the output.. 20pF should be fine.
Let me know if you have more questions, please.
Thanks Miguel, resetting the device did the trick. Is there anyplace that I can get a little more information on how to configure the evaluation board?
I would not have known to set the sign bit option to "phase accumulate" to produce a square wave if you had not tipped me off.
For example, once it has been programmed to generate the proper frequency, can I now disconnect it from the computer/SDP programmer and test the board using an external power supply?
Do I make connections to the AGND/AVDD or to the DGND/DVDD?
What should the input voltage range be?
Sorry, lots of questions but, as I said, the user guide is completely useless.
All this details are provided in the DS.
Answering you question, you can disconnect the board form the SDP but you need to include a pull-up resistor in the FSYNC pin.
Additionally, remember that you should power the board externally.
