Claim Text:
1. A probe module, which is provided between a printed circuit board (PCB) and a device-under-test (DUT) to perform a loopback test, comprising: a substrate having two first connecting circuits and two second connecting circuits, wherein an end of each of the first connecting circuits is electrically connected to the PCB; a probe base provided between the substrate and the DUT; two probes embedded in the probe base, wherein each of the probes has two opposite ends exposed outside of the probe base to be connected to an end of one of the second connecting circuits and to contact a tested pad of the DUT respectively; two signal path switchers provided on the probe base, wherein each of the signal path switchers is electrically connected to another ends of one of the first connecting circuits and one of the second connecting circuits; and a capacitor provided on the probe base, wherein two ends of the capacitor are respectively electrically connected to the signal path switchers; wherein the probe base is hollow, and the signal path switchers and the capacitor are either provided on a surface of the probe base which faces the substrate or received in the probe base.
