Description

technical field [0001] The invention relates to a signal generator, in particular to an analog signal generator used in the ground static test of an automatic safety protection device for large-scale transportation equipment. Background technique [0002] All kinds of large-scale transportation equipment such as spacecraft, ships, railway locomotives and EMUs need to do static tests when they are newly manufactured or overhauled or routinely inspected. The static test of various transportation equipment is to simulate the equipment when it is put into operation. various situations that may be encountered. Taking the railway locomotive as an example, the static test items include the status signal of the locomotive itself, the signal of the railway line and other safety signals that must be considered. At present, the static test of a railway locomotive needs multiple equipments to work together. Although it can meet the test requirements in some cases, there are obvious sho...
