    摘要： Testing microelectronic devices using electro-optic modulator probes is disclosed. In one aspect, a testing apparatus may include an electrical signaling medium to exchange electrical signals with a microelectronic device. The testing apparatus may include an electro-optic modulator probe to provide optical signals that are modulated by the electrical signals. An optoelectronic transducer may be included to convert the modulated optical signals to modulated electrical signals. The testing apparatus may further include a logic analyzer module to receive and analyze the modulated electrical signals. Other testing apparatus are disclosed, as well as systems incorporating such apparatus, and various methods of testing microelectronic devices.
