Signal generation device with matched signal paths and output control
A recently granted patent (Publication Number: US12000889B2) discloses a signal generation device that includes at least two signal generators and a clock source providing a clock signal to each generator. The signal paths are matched for signal runtime, and each generator can adjust its output signal based on amplitude or phase correction factors provided by signal comparators. The device can generate arbitrary signals, sine signals, and includes components like attenuation/amplification units or phase shifters. It can be used in oscilloscopes or frequency response analysis devices, offering configurable phase offset, amplitude, or amplitude offset for output signals.
Furthermore, the patent covers a measurement device incorporating the signal generation device for testing devices under evaluation. The measurement device includes signal generators, a clock source, and signal measurement inputs to measure signals generated by the device under test. The device can output a differential signal to the device under test and includes a signal processor to calculate the frequency response based on the output signals and measured signals. The method for operating the signal generation device involves generating a clock signal, providing it to the signal generators, measuring and adjusting the output signals based on amplitude or phase correction factors, and can be used with arbitrary signal generators, sine signal generators, or devices with attenuation/amplification units or phase shifters. The method also includes measuring signals from the device under test for further analysis.
