Problems solved by technology
[0005] However, since the multi-function signal device integrates a large number of signal modules, its volume is generally large, and it is connected with the TV to be tested by cables. It is very inconvenient to connect or disassemble multiple interfaces during the test, and the test efficiency is very low. Low

Description
technical field [0001] The invention relates to the technical field of testing, in particular to a signal generating device, a signal collecting device and a testing system. Background technique [0002] When testing the device as a whole, it is necessary to provide some input to the device and check whether its output meets the requirements to determine whether the device is qualified. [0003] In the test of the whole TV set, since the TV set has more and more functions, there are also many interfaces that can be supported. Therefore, when the whole set of the TV is tested, a multifunctional signal device capable of providing multiple signals must be configured to provide a test signal for the TV. [0004] In addition to being connected to the multi-function signal device, the TV also needs to be connected to other devices participating in the test, such as test devices and servers, so as to facilitate test control, data recording and sorting of a large number of TV produ...
