I use ADS7-V2 to eval the AD9164。it need to use the DPGdownload。it is successful。can I know what data is generated by DPG?
DPG Downloader is a Pattern generator which is part of DAC software suit developed by Analog Devices. It can generate number of waveform including but not limited to "DC, single tone, multi tone, chirp, cable and wireless infrastructure waveforms and the list goes on. Also, the user can generate own pattern.
YES，I can use the single tone mode, and i know it is working well by using Spectrum Analyzer。i just want to know the specific data generated by DPG( i mean the Waveform data of the digital domain).
Some of our patterns are protected by IP and we can't share the details. Would you please let us know which pattern are you specifically interested in in order for me to see if I can help you with.
thank you! In fact, we are interested in the purity of spectrum. we used a FPGA to give data to AD9164 through JESD204B( 12.5 Gbps, 8 Lanes, M = 1 , no interpolation ). The data in FPGA is created by matlab(i write the code). But i found the spectrum is worse comparing with the spectrum using ADS7-V2 + AD9164(DPG Downloader use the single tone mode).So i want to know if you can let me know what's your data.
Actually，I am trying to compensate the dynamic nonlinearity of AD9164 by digital predistortion, so that we can get a more pure spectrum. So i wonder if you can provide some date of dynamic nonlinearity of AD9164 because I don't have enough good equipment in my lab to measure enough accurate data.
