Use the HDL-optimized Channelizer block to process incoming analog-to-digital converter (ADC) samples and produce a spectrum that has 512 MHz of bandwidth. MATLAB® displays the resulting spectrum plot by using FPGA API functions over a TCP/IP connection. The channelizer data sent back is in limited bursts, which are triggered by an AXI4 register in a capture loop. The model also contains an interface to the digital-to-analog converter (DAC) by using a numerically-controlled oscillator (NCO) to drive a tone commanded at some frequency over AXI4.

Use multi-tile synchronization (MTS) to resolve the time alignment issue of multiple channels across different tiles on an RFSoC device. The RFSoC has built-in features that enforce the time alignment for samples of multiple channels across different tiles. Channels in a tile alone are aligned in time but a guarantee of alignment with another channel from a different tile does not exist. You can enable multi-tile synchronization (MTS) to correct for this issue by first measuring latency across different tiles and then applying sample delays to ensure samples align correctly.
