Abstract:
1. A method for collecting and displaying signal waveform, by at least one processor configured as a control measuring unit and an automatic collecting unit, the method comprising: the control measuring unit determining a corresponding test command and test parameter according to selection of test points on a tested object, calculating a position coordinate of each test point, and sending the test command and the test parameter to the automatic collecting unit; the automatic collecting unit returning test signals of each test point collected by a collecting probe to the control measuring unit according to the test command and the test parameter; and the control measuring unit generating corresponding waveform data according to the test signals returned by the automatic collecting unit, storing and displaying the waveform data; wherein, the control measuring unit determining the corresponding test command and the test parameter according to the selection of test points on the tested object comprises: the control measuring unit selecting a corresponding type of collecting probe according to variety, frequency and amplitude of signals of each test point of the tested object, and setting test parameters of vertical and/or horizontal and triggering of each data channel; the control measuring unit calculating the position coordinate of each test point comprises: calculating out the position coordinate of each test point according to detected original position coordinate of the tested object; the control measuring unit sending the test command and the test parameter to the automatic collecting unit comprises: sending the test command and test parameter including at least the position coordinate of the test point and the selected probe to the automatic collecting unit; the automatic collecting unit returning the test signals of each test point collected by the collecting probe to the control measuring unit according to the test command and test parameter comprises: the automatic collecting unit sending the selected probe to a specified position according to the position coordinate of the test point in the test command, carrying the probe to a specified position coordinate to contact with the corresponding test point by forming a multi-coordinate motion trajectory, and returning the test signals collected by the probe to the control measuring unit; and the control measuring unit generating corresponding waveform data according to the test signals returned by the automatic collecting unit, storing and displaying the waveform data comprises: the control measuring unit receiving the test signals of one or more test points returned by the automatic collecting unit through one or more set data channels, generating the corresponding waveform data, and storing and displaying the waveform data.
