Abstract

The invention provides a signal sampling device and a signal sampling calibration method, belonging to the technical field of signal sampling equipment. The signal sampling device includes: an optical modulation multiplexer, a plurality of sampling conversion modules and a main control module; the optical modulation multiplexer is used for coupling with an external signal source, and each sampling conversion module is respectively connected to the optical modulation multiplexer and the main control module coupling. By completing the modulation and division of the original signal in the optical path of the optical modulation multiplexer, it effectively avoids the distortion of the signal transmitted in the circuit, and will not generate unnecessary spurious and interference due to the influence of the nonlinear circuit, and improves the sampling rate. accuracy and sampling efficiency. In addition, through the calibration of the clock signal by the main control module, it effectively avoids the error generated by the hardware process, and thus effectively improves the sampling accuracy.

Description

technical field [0001] The present invention relates to the technical field of signal sampling equipment, in particular to a signal sampling device and a signal sampling calibration method. Background technique [0002] With the development and improvement of science and technology, devices and techniques for signal sampling have been widely used. [0003] In the prior art, signal sampling can be performed through an analog-to-digital converter. Although its structure is simple and its cost is low, its application range is limited due to its low sampling frequency and sampling efficiency. In addition, multiple channels can also be used to sample the signal. Although multi-channel can increase sampling efficiency, for signals with too wide bandwidth, the sampling circuit will often fail to work normally, which in turn limits its application range. In addition, in the prior art, a mixer can also be used to facilitate sampling of high-frequency signals. However, the use of m...
