A system for providing data communication is disclosed. The system includes a computer test tool configured to perform one or more diagnostic tests on a computer network and a cloud-based server. The cloud-based server is configured to couple to the communication network so as to exchange data with the computer test tool when the computer test tool is coupled to the communication network. The cloud-based server tracks usage of the computer test tool and, based on the tracked usage, transmits a message to the computer test tool that temporarily enables the computer test tool based on a predetermined condition.

The present application discloses a test lead assembly and a measurement device. The test lead assembly comprises: a first test lead having a first cable extending between a distal end and a proximal end, a first test probe attached to the distal end and a first plug attached to the proximal end; a second test lead having a second cable extending between a distal end and a proximal end, a second test probe attached to the distal end, and a second plug attached to the proximal end; and a fastener member for repeatedly releasably engaging at least a portion of the first cable with at least a portion of the second cable along a length of the first and second cables. The test lead assembly and the measurement device of the application can avoid or at least reduce knotting of the test leads.

Systems and methods directed toward combining visible light and infrared images can include processing visible light image data to determine an edge factor value for a plurality of visible light pixels corresponding to the strength of an edge at that location. The edge factor value can be determined using features from the visible light image data and an edge gain input, which may be adjustable by a user. The edge factor values are combined with an edge midscale value to create a first set of modified visible light image data including pixels emphasized based on the strength of the edge in the visible light image. The modified visible light image data is combined with infrared image data to create combined image data having contribution from the infrared image data and the edge factor values from the visible light image data.

The present application discloses a measurement device and method. The device comprises: a controller for controlling performance of a test on a test object; a signal generator for generating a signal indicative of an audible prompt to audibly identify a test result of the test object; and a signal transmitter for wirelessly transmitting the signal indicative of the audible prompt to a device remote to the measurement device.

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.


An apparatus for determining optical fiber array polarity is disclosed. The apparatus may be used to determine optical signal loss or intensity. An adapter may be used to couple the apparatus to a variety of optical fiber connectors. The apparatus includes a position sensing detector and processing circuitry. The position sensing detector includes a sensor that receives optical signals and electrodes that output respective output signals in response to receipt of an optical signal. The processing circuitry receives the output signals and identifies locations at which the optical signals were incident on the sensor. The processing circuitry also determines the receiving position in the optical array of an optical fiber and a polarity of the optical array based on the receiving position and a corresponding transmitting position. The processing circuitry may determine an intensity or loss of the optical signal based on an aggregate of the output signals.


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.

A clamp meter includes a meter body (102) and a clamp jaw assembly (104) mounted to the meter body. The clamp jaw assembly (104) includes a first clamp jaw (108) and a second clamp jaw (110) which are movable in relation to each other between a closed position and an open position. In the closed position, distal ends of the first and second clamp jaws (108a, 110a) meet to define an enclosed area between the first and second clamp jaws, and in the open position, the distal ends of the first and second clamp jaws (108a, 110a) are separate from each other to define a gap (112) allowing a wire under test to pass therethrough. The clamp meter further includes a locking member (116) mounted within the meter body (102). The locking member is operable to releasably lock the first and second clamp jaws (108a, 110a) in the closed position.

One or more embodiments are directed to camera probes and methods for visually inspecting an endface of an optical communication link, such as a fiber optic cable. Generally described, the camera probes and methods are directed to projecting light to an endface of the optical communication link from a first direction and at a first angle of incidence and projecting light to the endface at a second direction and at a second angle of incidence. A defect on the endface casts a first shadow when the light is projected in the first direction and a second shadow when the light is projected in the second direction. At least one of the first and second shadows is analyzed to determine its length. Using the length of the shadow and the known angle of incidence at which the light is projected, a height or depth of the defect is determined.
