Part Number: DAC38RF82
I have to generate the two chirp signals simultaneously from each DAC of the Dual DAC chip: DAC38RF82. The Chirp Signals are 1.92GHz ± 800MHz and 1.92GHz ± 950MHz using a DAC Clock frequency of maximum 9GHz.
Kindly confirm if this is possible, If yes, what is spurious and harmonic supressions levels.
If not possible, what is maximum bandwidth we can achieve for the both the chiro generations in DAC38RF82.
To clarify your question, are you wanting to generate one chirp, 1.92GHz ± 800MHz, from DAC A and the other chirp, 1.92GHz ± 950MHz, from DAC B. Or are you trying to have both DAC A and DAC B produce both chirps.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to David Chaparro:
The requirement is to generate one chiro, 1.92GHz ± 800MHz, from DAC A and the other chirp, 1.92GHz ± 950MHz, from DAC B. The DAC A and DAC B shall be operating simultaneously..
In reply to ARUNA NEELI:
Thank you for the clarification. We are looking into this and will let you know what we find.
Could you please help get the HSDC captures of the following JMODES. This will help the customer in the DAC selection.
Unfortunately it is not possible to produce both chirp signals at those bandwidths while in dual DAC mode. For dual DAC mode the maximum data rate is 1250MSPS complex per channel and this only supports a bandwidth of 1000MHz.
If you are to run the DAC in the Wideband DUC mode you would be able to have the bandwidth that you require, but you would be limited to a single output. You would need another device for the second chirp signal.
I did run one test on the Wideband DUC mode, 82121, and sent 10 tones over a 1.8GHz BW. The NCO was at 1.9GHz as requested. Here is what it looks like on a spectrum analyzer.
Thank you for your clarification.
