Abstract: A mechanism is included for receiving a phase modulated optical signal. The phase modulated signal is modulated by a remote electrical test signal at a sensor head. A reference optical signal is also received. A phase difference between the phase modulated optical signal and the reference optical signal is then determined. The phase difference is employed to recover the remote electrical test signal from the sensor head. The phase difference may be determined by employing a phase modulator in a controller that tracks a phase modulator in the sensor head. The phase difference may also be determined by comparison of the signals in the complex signal domain.

Abstract: An electro-optical sensor comprises an optical input configured to receive an optical carrier via an upstream fiber. The electro-optical sensor also includes an optical modulator configured to modulate an electrical signal onto the optical carrier to create an optical signal. The electro-optical sensor further includes an optical output configured to transmit the optical signal via a downstream fiber. The electro-optical sensor employs a variation output configured to transmit variation data indicating variation in the received optical carrier to support compensation for corresponding variation in the optical signal.

Abstract: A test and measurement system including an electro-optical accessory with an electro-optical sensor configured to output a modulated output signal, a device under test connected to the electro-optical accessory with a variable input signal, and a processor. The electro-optical accessory includes two sets of electrodes in which a sensitivity of the first set of electrodes is different from a sensitivity of the second set of electrodes. The processor in the test and measurement system is configured to modify the modulated output signal from the electro-optical voltage accessory to reconstruct the variable input signal of the electro-optical voltage accessory that exceeds the linear input range of the optical sensor.
