Tektronix pushes real-time-DSO bandwidth to 7 GHz

摘要

The maximum bandwidth of real-time-sampling DSOs stood at 6 GHz for more than a year with entrants from LeCroy (www.lecroy.com) and Agilent (www.agilent. com) joining a unit that Tektronix introduced. However, Tek's 6-GHz unit differed significantly from those of its competitors. With a maximum memory depth of 125k samples/channel (250k samples/channel with one or two channels active), it lacked the deep memory of the competitive units (now as great as 96M samples/channel on one or two channels in certain LeCroy scopes). Those who wanted an ultrawideband, deep-memory DSO from Tektronix had to settle for a 4-GHz bandwidth unit with single-channel-mode memory as deep as 32M samples/channel.
