Abstract

The invention discloses a signal interface adapter and relates to a signal interface adapter. The signal interface adapter is used for signal adaption of a test interface of a test system. The defect that the existing signal interface adapter is not universal is overcome. The signal interface adapter comprises a tested object end interface circuit (4), a plurality of replaceable signal adapter circuit plugboards (5), a test system end interface circuit (6), a slot (7) and a power supply system (8). One bidirectional signal transmission port of the tested object end interface circuit (4) is connected with one bidirectional signal transmission port of the slot (7). The other bidirectional signal transmission port of the slot (7) is connected with a bidirectional signal transmission port of the test system end interface circuit (6). The power supply system (8) supplies power to the slot (7). The replaceable signal adapter circuit plugboards (5) can all be plugged in the slot (7) so as to complete connection with the slot (7).

Description

technical field [0001] The invention relates to a signal interface adapter. Background technique [0002] Such as figure 1 As shown, the signal interface adapter 2 introduces the signals of the object under test 1 into the test system 3, and provides functions such as various stimuli, signal transfer and conversion, signal measurement matching, isolation, indication, and control for the object under test 1. . [0003] Since the types and characteristics of the signals input by each tested object 1 to the test system 3 are different, and the excitation, transfer and conversion circuits required by the tested object 1 are different, the specific circuit structure of the signal interface adapter 2 is different. The same, so it is difficult to achieve the versatility of the signal interface adapter. Contents of the invention [0004] The purpose of the present invention is to provide a universal signal interface adapter to solve the shortcoming that the existing signal adap...
