Abstract: Analysis systems can include both a test and measurement tool for generating measurement data representative of at least one parameter of a device under test and an imaging tool for generating image data representative of a target scene. An electrical isolation mechanism can electrically isolate a user operating the analysis tool from the test and measurement circuit through the imaging tool. The electrical isolation mechanism can include an insulating coating surrounding a part of the imaging tool having an opening proximate the imaging tool so that electromagnetic radiation can enter through the opening and reach the imaging tool. The opening can be sized so that a standard finger cannot penetrate the opening to within a predetermined distance of the imaging tool. Additionally or alternatively, a window positioned over the opening can prevent access to the imaging tool via the opening.

Abstract: Systems and methods for measuring alternating current (AC) voltage of an insulated conductor (e.g., insulated wire) are provided, without requiring a galvanic connection between the conductor and a test electrode or probe. A non-galvanic contact (or “non-contact”) voltage measurement system includes a conductive sensor, an internal ground guard and a reference shield. A common mode reference voltage source is electrically coupled between the internal ground guard and the reference shield to generate an AC reference voltage which causes a reference current to pass through the conductive sensor. At least one processor receives a signal indicative of current flowing through the conductive sensor due to the AC reference voltage and the AC voltage in the insulated conductor, and determines the AC voltage in the insulated conductor based at least in part on the received signal.

Abstract: A system providing a power source includes an electrical input and multiple electrical outputs. The electrical input is couplable to a current clamp that selectively clamps around at least one electrical conductor. A transformer coupled to the electrical input receives an input electrical signal from the at least one electrical conductor and produces an output electrical signal that is electrically isolated from the input electrical signal. Conversion circuitry electrically converts the output electrical signal to a converted electrical signal that is usable to power multiple electrical devices. Distribution circuitry distributes the converted electrical signal to the multiple electrical outputs, wherein each electrical output is couplable to an electrical device to provide power to the electrical device.

Abstract: Analysis systems can include both a test and measurement tool for generating measurement data representative of at least one parameter of a device under test and an imaging tool for generating image data representative of a target scene. A processor in communication with the test and measurement circuit and the imaging tool can process measurement data and image data. Isolation circuitry can be configured to provide isolation between the imaging tool and the test and measurement circuit while permitting communication between the processor and each of the test and measurement tool and the imaging tool. A display for presenting measurement data and/or image data can be electrically isolated from the test and measurement tool.
