Digital oscilloscopes capture 25-Gsamples/s on four channels

Tektronix has introduced the four-channel DPO70000 digital phosphor oscilloscope and DSA70000 digital serial analyzer with bandwidth options of 4 GHz, 6 GHz, or 8 GHz. All models include the high-end functionality of Tek's TDS6000C.
The oscilloscopes provide the bandwidth necessary for high-speed digital applications. The serial analyzers suit first-generation high-speed multi-lane and multilayer serial bus applications. For example, the 8-GHz analyzer captures the fifth harmonic of the highest frequency clock for high-speed serial buses up to 3.125 Gbps, such as PCI-Express, SATA, and XAUI.
With 25-Gsamples/s capture on four channels simultaneously, the 4-GHz bandwidth models have a rise time of 35 ps (typical) and a jitter noise floor down to 400 fs rms (typical). Standard memory per channel is 10 Mbytes for the oscilloscopes and 20Mbytes for the analyzers. Both instruments support memory configurations up to 100 Mbytes/channel, which equates to 4 ms at full real-time sample rate and 40-ps single-shot sample interval.
