Abstract
A testing system includes a computer (10) and a signal switching adapter (30). The computer includes a test signal generating element (19) and a microprocessor (15). The test signal generating element is capable of generating an original test signal. The microprocessor (15) is capable of communicating with the test signal generating element. A video card (11) is capable of receiving the original test signal from the microprocessor and outputting a to-be-displayed analog signal. The signal switching adapter includes an A/D converter (32). The A/D converter is capable of converting the to-be-displayed analog signal to a digital display signal. The signal switching adapter is capable of outputting the digital display signal back to the microprocessor.
Claims13
A testing system comprising:
- a computer comprising:
- a test signal generating element being capable of generating an original test signal;
- a microprocessor being capable of communicating with the test signal generating element;
- and
- a video card being capable of receiving the original test signal from the microprocessor and outputting a to-be-displayed analog signal;
