Welcome to like, coin 🤣🤣

The oscilloscope part uses two AD9288s (dual 8-bit 100M sampling rate ADCs), and uses alternating sampling to enable the oscilloscope to achieve a maximum sampling rate of 400Msps for a single channel and 200Msps for a dual channel.

The waveform generator uses 3PD5651 with a conversion rate of 125M, a data bit width of 10 bits, and a maximum sine wave output of 20MHz. The output of the waveform generator can be directly connected to the oscilloscope section through a double-headed BNC cable for oscilloscope testing.

The hardware part of the system consists of FPGA core board, portable oscilloscope baseplate, portable oscilloscope display board, and extended Data Acquisition module.

FPGA Core Board: Logic Function Implementation (Altera FPGA Cyclone IV EP4CE30);

Portable oscilloscope baseplate: preprocessing waveforms and generating arbitrary signals.

Portable oscilloscope display panel: Combining functions and directional buttons to achieve different operations, LCD displays information.

Expand Data Acquisition Module: Expand the AD9288_ADC module, and the analog front-end circuit is the same as the baseplate.
