Abstract

The purpose of this paper is to compare transient responses of all of the various ultrafast sampling oscilloscopes. This study was limited to the fastest samplers with transition durations (10-90% risetimes) of <35 ps and corresponding bandwidths of >10 GHz. It is very important for users of these instruments to realize that none of them will give the correct answer when measuring picosecond domain signals. The same pulse signal measured with different samplers will result in different pulse waveforms as displayed on the CRT's.
