摘要： A attachable/detachable probing tip system (10) has a housing (12) that includes a probing tip mounting member (14) and opposing substantially orthogonal attachment (16, 18) arms extending from the probing tip mounting member. The attachment arms define an inner surface of the probing tip mounting member in which is disposed at least a first a non-compressive set, resilient member (56). First and second probing tips (42, 44) are disposed over the non-compressive, resilient member (56) and secured to the housing by latching means (60, 66, 92, 96, 100, 130). The attachable/detachable probing tip system allows mounting of the probing tips (42, 44) to probing contacts on a device under test without a probe body or probing tip member (38) being attached. The attachment arms (16, 18) allows a probe body or probing tip member (38) to be attached and detached to the probing tip system (10). The probing tip member (38) includes contact pins that engage contact areas (82, 82, 92) of the probing tips (42, 44).

摘要： A wide bandwidth attenuator input circuit for a measurement probe has a Z0 attenuator circuit coupled in series with a compensated RC attenuator circuit. The series attenuator elements of the Z0 and the compensated RC attenuator circuits are coupled via a controlled impedance transmission line to the shunt attenuator elements of the Z0 and the compensated RC attenuator circuits. The shunt element of the Z0 attenuator element terminates the transmission line in its characteristic impedance. The junction of the series and shunt attenuator elements are coupled to the input of a buffer amplifier. At low and intermediate frequencies, the compensated RC attenuator circuit attenuates an input signal while at high frequencies, the compensated RC attenuator circuit acts as a short and the Z0 attenuator circuits attenuates the input signal.

摘要： A probe comprises a small “consumable” probe substrate permanently mounted to a circuit-under-test. The probe substrate includes a high-fidelity signal pathway, which is inserted into a conductor of the circuit-under-test, and a high-bandwidth sensing circuit which senses the signal-under-test as it propagates along the signal pathway. The probe substrate further includes a probe socket for receiving a detachable interconnect to a measurement instrument. Power is alternatively supplied to the probe by the circuit-under-test or the interconnect. When the interconnect is attached, control signals from the measurement instrument are supplied to the sensing circuit and the output of the sensing circuit is supplied to the measurement instrument. In one embodiment, the sensing circuit uses high-breakdown transistors in order to avoid the use of passive attenuation. In a further embodiment, the sensing circuit includes broadband directional sensing circuitry.

摘要： A signal acquisition probing system uses a micro-cavity laser to acquire an electrical signal from a device under test. The micro-cavity laser has a VCSEL gain medium and an electro-optic optical resonant cavity. The micro-cavity laser is pumped by an external laser source and generates a frequency modulated optical signal derived from the device under test electrical signal creating an electro-magnetic field distribution in electro-optic material in the micro-cavity laser that overlaps the optical path of the optical signal propagating in the electro-optic material. The frequency modulated optical signal is coupled to an optical receiver which converts the frequency modulated optical signal to an electrical signal. The electrical signal is coupled to measurement test instrument for processing and displaying of the electrical signal.

摘要： A variable attenuation signal acquisition probing system and voltage measurement system uses an optical cavity to acquire a signal under test. The probing system has an optical transmitter and receiver that are coupled to the optical cavity via an optical transmission system. The optical cavity has an electrode structure having apertures formed in the optical cavity that are parallel to propagation path of the optical signal within the cavity. A modulated optical signal is generated by the optical cavity in response to the signal under test creating an electro-magnetic field distribution in electro-optic material in the optical cavity that overlaps the optical path of the optical signal propagating in the optical cavity which varies the index of refraction of electro-optic material in the optical path. Changes in the polarization state of the optical signal attenuates the magnitude of the output electrical signal of the optical receiver.
