Abstract: A test and measurement system including an electro-optical voltage accessory with an electro-optical sensor configured to output a modulated output signal, a device under test connected to the electro-optical voltage accessory with a variable input signal that exceeds a linear input range of the optical sensor, and a processor. The processor 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.

Abstract: A method of controlling the gain or sensitivity of a test and measurement system. The test and measurement system includes a host, a controller with an optical transmitter and an optical receiver, optical-to-electrical converter, an accessory head, and a device under test. The method includes determining whether a gain or sensitivity adjustment of the test and measurement system is required, determining the amount of gain or sensitivity adjustment, and adjusting the output power of a laser of the optical transmitter in response to the determination of the gain or sensitivity adjustment of the test and measurement system.
