Abstract: Systems and methods for measuring a characteristic of an analog signal are provided. A system for measuring a characteristic of an analog signal includes an analog to digital converter that is configured to convert an analog signal into a digital form that includes at least one digital data value, and logic that is configured to associate a data tag with the data value.

Abstract: Systems and methods for wideband single-end probing of variably spaced probe points are provided. One such embodiment includes a probe housing. The probe housing at least partially surrounds a probe barrel. A probe barrel end cap extends from the probe barrel and at least partially surrounds a probe tip. The longitudinal axis of the probe tip is offset from the longitudinal axis of the probe barrel. A ground tip is adjacent to the probe tip and electrically connected to the probe barrel. Methods are also provided.

Abstract: Systems and methods for wideband active probing of devices and circuits in operation are provided. One such embodiment includes a probe amplifier housing that at least partially contains a probe amplifier circuitry. The probe amplifier circuitry and the probe housing are configured to be separately arranged and positioned from connected probing and signal monitoring apparatuses. Methods are also provided.

Abstract: A probe for connecting a device under test to a measurement device that corrects for dc errors and noise generated by the current flowing through the ground shield of a transmission line used by the probe. The probe identifies a voltage drop in the ground preferably using an additional line between the device under test and the measurement device. The signal provided to the measurement device is corrected based on the identified voltage drop.

Abstract: A probe apparatus with a probe network consisting of two electrical paths. One path is a dc path and the other path is an ac path. The separation of the dc and ac currents allows wide-band probing of circuits with a low mass probe tip that has acceptable input impedance.
