Real-time oscilloscope with a built-in time domain reflectometry (TDR) and/or time-domain transmission (TDT) function

A real-time oscilloscope with a built-in time domain reflectometry (TDR) and/or time-domain transmission (TDT) function for measurements of a device under test (DUT), comprising:

• at least one built-in generator, and
• at least one real-time measurement channel,
• wherein the built-in generator is in communication with the real-time measurement channel and the device under test (DUT) and is configured to generate incident signals,
• wherein the real-time measurement channel is configured to capture incident signals transmitted to and reflected by and/or transmitted by the device under test (DUT),
• wherein the built-in generator includes a generator source and an output line with pick off, and
• wherein a first port of the output line is connected to the generator source, a second port of the output line is connected to a first port of the built-in generator and the pick-off is connected to a second port of the built-in generator.

A method for performing time domain measurements with a real-time oscilloscope the method comprising the steps of:

• generating an incident signal with the aid of a built-in generator,
• transmitting the incident signal to a device under test (DUT),
• measuring a reflection signal of said incident signal at an input of the device under test (DUT) and measuring a transmission signal of said incident signal at an output of the DUT,
• acquiring incident signals transmitted to and reflected and/or transmitted by the device under test (DUT) with the aid of a real-time measurement channel, and
• triggering on non-synchronized incident signals transmitted to, reflected and/or transmitted by the device under test (DUT).
