|Title:||Correcting sampling oscilloscope timebase errors with a passively mode-locked laser that is phase-locked to a microwave oscillator|
|Published:||April 01, 2010|
|Abstract:||In this paper, we describe an apparatus for correcting the timebase errors when calibrating the response of an equivalent-time sampling oscilloscope using a passively mode-locked erbium doped fiber laser that is phase locked to a microwave signal generator. This enables us to simultaneously correct both the random jitter and the systematic timebase distortion in the oscilloscope. As a demonstration of the technique, we measure the electrical pulse generated by a fast photodiode that is excited by our laser. We show that the pulse that is reconstructed using our technique has significantly lower uncertainty that the pulse that is reconstructed using a separate correction for timebase distortion followed by jitter deconvolution.|
