Problems solved by technology
For the PXIe chassis system using all NI boards, although the standardization and integration of control software has been greatly improved compared with discrete instruments, certain programming support is still required
Moreover, since there is no direct data exchange path between each board, the ability of each part of the system to adjust in real time is poor, and the coordination is low

Correspondingly, the embodiment of the invention further discloses a control method of the signal generation and reading device.
Description
technical field [0001] The invention relates to the technical field of signal processing, in particular to a signal generation and readout device and a control method. Background technique [0002] In recent years, with the continuous advancement of technology and the continuous advancement of research in various fields, high-performance signal generation and readout devices have been widely used in physics, chemistry, biology, medicine, engineering and other fields. The types of signals required have developed from the original sine wave, periodic square wave, triangle wave, sawtooth wave and other regular special waveforms to arbitrary waveforms and ultra-high-precision and high-complexity pulse sequences, and then derived arbitrary waveform generators (AWG, Arbitrary Waveform Generator), arbitrary sequence generator (ASG, Arbitrary Waveform Generator) and other dedicated signal generating devices. The acquisition of signals has also developed from simple charge recording...
