A probe or accessory for use with an electrical test and measurement instrument can include an input to receive an input signal from a device under test (DUT), a clamp control unit or oscilloscope to apply a clamping/limiting level to the input signal to generate an output signal, and/or a control unit output port to provide the clamped/limited output signal to an oscilloscope.

The disclosure relates to a method and system for intelligent visualization in the monitoring of process and/or system data used in technical processes and in the operation of technical systems. The behavior of signals in the past is analyzed and used for a future optimized visualization. Continuously running online algorithms support the system operator by detecting and correspondingly highlighting deviations from the historically observed signal patterns.

A computer implemented method for determining a timing variation for an edge of a waveform under simultaneous switching noise (SSN) conditions is provided. The method includes characterizing an impact of mutual inductive relationships on a pin while the pin is at a quiet state and characterizing a signal edge applied to the pin. The signal edge can be characterized by the slew rate in one embodiment. A voltage change related to a curve characterizing the impact of mutual inductive relationships is identified and the voltage change is applied to a curve characterizing an impact of SSN on the signal edge. The method includes calculating a timing variation correlated to the voltage change applied to the curve characterizing the impact of SSN on the signal edge and presenting the calculated timing variation.
