1. A probe device, comprising:
a first receiving terminal configured to receive a multi-level signal having M levels, where M is a natural number greater than 2;
a second receiving terminal configured to receive a reference signal;
a receiving buffer including a first input terminal connected to the first receiving terminal, a second input terminal connected to the second receiving terminal, and an output terminal configured to output the multi-level signal based on signals received from the first input terminal and the second input terminal; and
a resistor circuit comprising a plurality of first resistors connected to the first receiving terminal and a plurality of second resistors connected to the second receiving terminal, and the resistor circuit configured to determine a magnitude of a termination resistance of the first receiving terminal and the second receiving terminal.
