Patent ID: 11898927
Assignee: TEKTRONIX, INC.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 0:
1. A test and measurement device, comprising:
one or more ports configured to connect to a device under test (DUT);
a time domain reflectometry (TDR) source configured receive a source control signal and to produce an incident signal to be applied to the DUT;
one or more analog-to-digital converters (ADC) configured to receive a sample clock and sample the incident signal from the TDR source and a time domain reflection (TDR) signal or a time domain transmission (TDT) signal from the DUT to produce an incident waveform and a TDR/TDT waveform;
one or more processors configured to execute code to cause the one or more processors to:
control a clock synthesizer to produce the sample clock and the source control signal, and
use a period of the TDR source, a period of the sample clock, and the number of samples to determine time locations for samples in the incident waveform and the TDR/TDT waveform; and

a display configured to display the incident waveform and the TDR/TDT waveform.
