Description
technical field [0001] The invention relates to the technical field of test and measurement, in particular to a high-voltage signal generating device based on a PXI bus. Background technique [0002] During the analog calibration process of a high-voltage radar test system, a standard DC voltage signal of up to 300V and an AC voltage signal of up to 115V / 400Hz are required for calibration, which are generally provided by the voltage function of a multi-function standard source. Because the test system often needs on-site measurement, and the multi-functional standard source is large in size, and the measurement of other functions is added, the standard instrument is not conducive to carrying. [0003] Since the advent of PXI bus technology, due to its high integration and ease of use, it has been used more and more in the field of test and measurement. At the same time, different types of PXI modular instruments have been developed, including some performance and desktop ins...
