4-4 Hardware Principle

32/64-channel transmission wave forms according to scanning time sequence and control
parameters.

32/64-channel transmission wave forms to 32/64-channel high-voltage transmission wave
by driver.

Echo receiving LNA is to enlarge fixed gain.

By the control of TGC, echo receiving carries out variable gain amplification by depth.

32/64-channel analog echo could be switched to 32/64-channel digital signal by ADC.

BF FPGA combines 64-channel echo signal to output to DSP FPGA, and DSP FPGA is
sent to signal processing to a single image which is uploaded to CPU module by
PCIE_PHY, then CPU module performs post processing.

PCI_PHY implements PCIE interface switching.

BF FPGA can communicate with the CPU module through transferring DSP FPGA.

The CPU module communicates with the probe board via BF FPGA.

DSP FPGA controls the 4D drive board to output the 4D signal to the probe board.
