Abstract: The present invention provides an electro-optical isolation system for coupling an electronic measuring device to a device under test for making accurate measurements of signals within a wide frequency range while the device under test is being subject to high power electrical disturbances. The invention provides an increased rejection of high common mode signals and reduction of undesired self-capacitance by implementing a shielded handheld transmitter unit having an integrated measurement probe. The transmitter unit converts the sensed signal to an optical signal which is transmitted through an optical medium to a receiver unit. Under control of a microprocessor, the level of the output signal from the transmitter unit is modulated by the signal received from the sensing probe. The microprocessor within the transmitter unit automatically controls the level of optical signal emitted by the optical converter, and further calibrates a driver circuit to maintain measurement accuracy. The modulated optical signal emitted by the electro-optical converter is communicated to the receiver unit by an optical fiber medium.

Abstract: The present invention provides for a method for configuring a laser operating system. More specifically, the system utilizes a graphical user interface (GUI) to allow an operator to interact with an embedded controller and set parameters for an optical communications transceiver. The system adjusts parameters such as laser bias and modulation currents, wavelength, qualification tests, and file management. In other words, the GUI manages configurations of a transceiver operating system. The system provides for an efficient method to design a laser transceiver and to perform and manage qualification tests. The embedded controller may contain a real time operating system that controls multiple functions in the transceiver and an optical channel. The GUI interacts with an operating system to download embedded firmware into an embedded micro controller unit (MCU). Downloading of firmware allows for multiple special programs from different sources to be integrated.

Abstract: An electro-optic interface system configured to communicate, via an optical channel, an electronic signal between a fist and second electronic system includes a first electro-optic transceiver, an optical channel and a second electro-optic transceiver. The first electro-optic transceiver includes a signal port coupled to the first electronic system and an output coupled to the optical channel and includes a first transceiver emulator circuit, and a first transceiver laser. The first transceiver emulator circuit is configured to receive an electronic signal comprising parallel data from the fast electronic system and, in response, produces the serialized data. The first transceiver laser produces a first modulated output signal corresponding to the electronic signal communicated from the first electronic system. The second electro-optic transceiver includes a first port coupled to the optical channel and a second port coupled to the second electronic system. The second transceiver includes a second transceiver photodetector, and a second transceiver emulator circuit.

Abstract: An electrical circuit includes a switch having an on state and an off state for connecting a single drive current power source in series with an electroluminescent device for each electroluminescent device of an electroluminescent device array to conduct a first drive current through the electroluminescent device in the on state. The switch connects an amplitude shift load in series with the electroluminescent device and the drive current power source to conduct a second drive current through the electroluminescent device in the off state. The first drive current and the second drive current constitute an amplitude shift modulated drive current through the electroluminescent device. A control signal generator receives a digital switch command for each electroluminescent device from an electroluminescent device controller and generates an amplitude shift control signal to cause the switch to switch between the on state and the off state for regulating an average of the amplitude shift modulated drive current.
