Latest Patents

“Multiplexing Instrumentation Preamplifier” describes an oscilloscope preamplifier with multiple inputs and outputs. A programmable cross-point multiplexer supports different operating modes, from connecting separate inputs to separate outputs to routing one input across multiple outputs to increase the sampling rate. A microprocessor controls switching amplifiers through programmed latches, while a voltage divider provides selectable attenuation levels.

“Programmable Delay for Digitizer Circuits” concerns converting analog waveforms displayed on a CRT screen into digital signals for storage. A microprocessor uses user-defined parameters to determine when the waveform is sampled. The design allows users to set sample resolution and position the sampling window, and to view that window on the CRT display before sampling begins.
