In this letter we report a new purely electrical correlation measurement technique permitting time‐resolved analysis of short electrical pulses. This technique provides a cheap and simple tool for measurements in the picosecond time domain, for instance, in the field of fast optoelectronics. In preliminary experiments, a time resolution of 26 ps has been obtained which exceeds the limits of conventional sampling oscilloscopes. The method offers the interesting advantage to be applicable to any short electrical pulse and does not require a synchronized optical pulse, in contrast to the optoelectronic correlation technique used so far in this time regime.
