62.8-GHz-bandwidth DSO has 75-fsec-rms jitter-noise floor
Dan Strassberg, Contributing Technical Editor - April 11, 2012
With two of its four channels active and the maximum 2G-sample/active channel acquisition-memory, Agilent's new Infiniium 96204Q real-time-sampling DSO takes 160G samples/sec on each active channel. At that sampling rate, it captures 12.5-msec-long records. The rms jitter-noise floor is 75 fsec. You can use the four-channel scopes as two-channel instruments to obtain maximum bandwidth and minimum rise time. Agilent allows you to combine four scopes into a system that accommodates 16 33-GHz channels or eight 62.8-GHz channels, but the waveforms, along with time-reference markers, appear on four separate LCDs, each of which measures more than 15 in. diagonally.
A key application for ultra-wideband scopes with large numbers of channels is measurements on multilane fiber-optic communication systems. Such measurements require optical-to-electrical converters. Expect scope manufacturers to soon offer multichannel versions of these converters as front-end devices for these ultra-wideband scopes. Prices for the Agilent 96204Q range from $191,000 to $419,000. Agilent has also introduced Infiniiview, a $750 PC-based software package that enables users to go offline and manipulate and analyze data that scopes capture online.
