Latest Patents
One of Kalev's latest patents is a "Serial data link measurement and simulation system." This system is designed for use on a test and measurement instrument and features a display device that presents a main menu with elements representing a measurement circuit, a simulation circuit, and a transmitter. The main menu includes processing flow lines that connect the measurement circuit to the transmitter and from the transmitter to the simulation circuit. Additionally, it has a source input to the measurement circuit and multiple test points for waveform acquisition. The simulation circuit also includes a receiver, allowing users to define both measurement and simulation circuits while tying all aspects of the serial data link system together.
Another significant patent is the "Transport delay and jitter measurements" method. This innovative approach utilizes a real-time oscilloscope and cross-correlation to measure transport delay and jitter. By acquiring waveforms from two test points in a system under test, the method runs clock recovery on both waveforms to determine respective rates and offsets. It computes a time offset between the two waveforms and filters the jitter to calculate a mean-removed cross-correlation coefficient. This method allows for precise adjustments of clock edges for comparison with data transition edges, ultimately measuring jitter effectively.
