The second end includes a first aperture defined therethrough, the first aperture having a first diameter, and a second aperture defined therethrough, the second aperture have a second diameter less than the first diameter.

A cable for monitoring current and voltage includes a plug, a socket, first and second conductors extending from the plug to the socket, a current and voltage monitoring module, a transceiver, and a housing. The current and voltage monitoring module is coupled to the first and second conductors, and is configured to measure current and voltage usage levels of the conductors. The transceiver is coupled to the current and voltage monitoring module and is configured to receive data related to the current and voltage levels and transmit the data related to the current and voltage levels. The housing is configured to house the current and voltage monitoring module, the transceiver and one of the socket and the plug.

A voltage probe holster includes a support member disposed on a base. The support member defines a plurality of apertures sized to receive a plurality of single-ended probes having coaxial leads. Each of the apertures have a conductive periphery configured to conduct electricity from one of the coaxial leads such that a common ground loop through the support member and the base is formed and that differences in ground potential are reduced.

Apparatus for testing a device by delivering an electrostatic discharge signal to one or more device terminals, comprising a first part configured for mechanically mounting the device and comprising one or more first part connectors for electrically coupling to the one or more device terminals and thus providing electrical access to the one or more device terminals, a second part comprising one or more second part connectors configured for electrically coupling the one or more first part connectors to the one or more second part connectors for testing the device via the second part connectors, and a guide arranged for mechanically moving the first part relative to the second part. The guide is configured to physically disconnect the one or more first part connectors from the one or more second part connectors while the electrostatic discharge signal is delivered to the one or more device terminals.

A probe for measurements on a device under test with low source impedance is described. The probe has a resistor coupled in series between a probe tip and a probe cable connected to a measuring apparatus. The resistor having an impedance equal to a characteristic impedance of the probe cable or equal to the difference between the characteristic impedance of the probe cable and an output resistance of the device under test. Further, a measuring system and a test setup are described.

A method of testing sensors includes providing a test sheet that includes a plurality of sensor assemblies, a plurality of test pads, and traces extending from the sensor assemblies to the plurality of test pads. A sensor is positioned on each sensor assembly. Each sensor is connected to the sensor assembly with wire bonds. An enclosure is formed over the plurality of sensor assemblies. An electrical signal is detected from each of the plurality of sensor assemblies at the test pads.
