Abstract:
An electro-optic sampling oscilloscope comprising:an electro-optic sampling probe;means for producing timing pulses;optical pulse generation means for generating optical pulses to produce laser beams at a time corresponding to a timing pulse and the optical pulse generation means supplies the optical pulses to said electro-optic sampling probe;receiving light amplification means for amplifying an output of the electro-optic sampling probe to produce a received light signal;sampling means for sampling the received light signal at a first prescribed time after production of a timing pulse to produce first signal data, said sampling means also sampling the received light signal at a second prescribed time after production of the timing pulse and after said first prescribed time to produce second signal data;subtraction means for performing subtraction to produce a difference between the first signal data and the second signal data; andmeans for displaying the output of the subtraction means.
