Modulation mode is not compatible with the current hardware architecture (many DDS cards on a backplane), because it requires a 32-bit-wide bus and this would cost us too many TTL lines on the LPC connector. If we want DDS chips with this direct modulation mode, they should be driven directly from a dedicated FPGA a few at a time. Is there anyone who needs this mode in the near term?
