Abstract:
1. A tester with low signal attenuation, suitable for measuring an electrical characteristic of a subject to be tested, the tester comprising: a circuit board having a first surface and a second surface, wherein the first surface has a first signal transmission line, and the second surface has a second signal transmission line; and a first probe having a contact end for contacting with the subject to be tested, a first signal end connected to the first signal transmission line, and a second signal end connected to the second signal transmission line, wherein the first probe receives a testing signal from the first signal transmission line through the first signal end, and transmits the testing signal from the contact end to the subject to be tested, such that the subject to be tested generates a response signal, and the first probe transmits the response signal to the second signal transmission line through the second signal end for measuring electrical characteristic of the subject to be tested.
