We describe two calibration methods of comb generator(CG) as harmonic phase reference, one is based on digital sampling oscilloscope(DSO) and the other is based on electro-optic sampling system(EOS).

Sampling oscilloscope with 4 channels (voltages from 0 to 5V), with frequencies up to 3kHz. It has a PWM signal generator and a square wave output. It can also automatically identify the resistor or ...

Over on his YouTube channel our hacker [CircuitValley] repairs an old TDS8000 scope. The TDS8000 was manufactured by Tektronix circa 2001 and was also marketed as the CSA8000 Communications Signal … ...

An ideal sampling oscilloscope for 224-Gb/s validation has extremely low intrinsic noise (<20 µW RMS) and jitter (<90 fs RMS) for the best optical accuracy and sensitivity. 112-Gbaud clock ...

In this letter, we report on a novel all-optical sampling scheme using cross-phase modulation-induced wavelength shifting and optical filtering. Up to 500-Gb/s optical signal eye-diagram measurements ...
