  • Method of CTLE estimation using channel step-response for transmitter link equalization test
    Patent number: 12339298
    Abstract: A method of automatically selecting a continuous time linear equalization (CTLE) filter includes capturing a response waveform for a channel of a communication link of a device under test (DUT), generating a set of candidate CTLEs, and automatically selecting the CTLE from the set of candidate CTLEs using the response waveform. A test and measurement instrument has a user interface, a port to allow the instrument to connect to a device under test (DUT), and one or more processors configured to execute code to cause the one or more processors to: generate a set of CTLE candidates; capture a response waveform for the channel; and automatically select the CTLE from the set of candidate CTLEs using the response waveform.
