Abstract: A probe module, which supports loopback test and is provided between a PCB and a DUT, includes a substrate, a probe base, two probes, two signal path switchers, and a capacitor. The substrate has two first connecting circuits and two second connecting circuits, wherein an end of each first connecting circuit is connected to the PCB. The probe base is provided between the substrate and the DUT with the probes provided thereon, wherein an end of each probe is exposed and electrically connected to one second connecting circuit, while another end thereof is also exposed to contact the DUT. Each signal path switcher is provided on the probe base, and respectively electrically connected to another end of one first and one second connecting circuits. The capacitor is provided on the probe base with two ends electrically connected to the two signal path switchers.
