Tektronix (www.tek.com) has unveiled its fastest oscilloscopes that come with a multi-chip module that offer an eight-way, 100 GS/s interleaved track, and a hold chip that features 33 GHz preamplifiers — the DPO/DSA73304D oscilloscopes.
Providing a maximum real-time sampling rate of 100 GS/s on two channels, and an analogue bandwidth of 33 GHz on four channels, the oscilloscopes also offer 10 terasamples equivalent time sampling.
The chips of the oscilloscopes have been specifically developed by IBM on its eight HP SiGe BiCMOS process. Unlike gallium arsenide, the SiGe technology allows bipolar transistors to be incorporated on similar die as standard CMOS.
The input of the oscilloscope is directly connected to 100 GHz SMPM connectors of the chip, effectively reducing the noise at the signal frequencies. Delivering the level of signal capture performance required for high speed optical characterization, the oscilloscopes measure signals with nine PS rise-times while RF and serial data measurements are taken with data rates of more than 20 Gbit/s.
Input sensitivity of the oscilloscope stands at 6.25mV/div (62.5mV full scale). Its trigger functions include a visual trigger capability as well as an 8b/10b serial decode capability. The oscilloscope also measures bounded uncorrelated jitter (BUJ).
Tektronix has also announced that a 30 GHz probe will also be made available next year.
With the first delivery of the oscilloscope set by the end of the year, oscilloscope users will have to make direct connections utilizing specialist test jigs or the current P7500 20GHz probe.
