Reply To: VSG25A narrow band QAM demodulation using SA series

[Andrew]

Hi Mervin,

For the SA and VSG devices, the symbol rate limitations on QAM16 are going to be between 16kS/s and 150kS/s. The VSG is capable of generating QAM64 and QAM256 patterns but the SA is not able to demodulate them currently. You can configure a QAM signal with up to 512 symbols. I have attached an image of this setup.

If you have further questions, let me know.

Regards,
A.J.
