Mixed-signal oscilloscopes go high end
Six new models of MSOs from Tektronix have analog bandwidths ranging from 4 GHz to 20 GHz at up to 50 Gsamples/s on all four channels. Each model also has 16 logic channels.

With the MSO70000 series of mixed-signal oscilloscopes and two optional logic probes, Tektronix has introduced its latest entry in the high-end oscilloscope market. The six models of MSOs (mixed-signal oscilloscopes) have analog bandwidths ranging from 4 GHz to 20 GHz at up to 50 Gsamples/s on all four channels. Each model has 16 logic channels. You can time synchronize logic and analog measurements for use in debugging ASICs, FPGAs, DDR memory devices, and digital RF devices.
The MSO70000 instruments come with 10 Msamples of analog memory for the three lower-bandwidth models and 20 Msamples for thethree high-bandwidth models. Maximum memory length for all modes is 250 Msamples. Timing resolution for the logic channels is 80 ps with a maximum record length of 250 Msamples.
Tektronix offers two options for logic probes. The P6717 has a 350-MHz bandwidth with single-ended channels, while the P6780 is a differential probe with 2.5-GHz bandwidth. That's fast enough for buses such as PCI Express.
You can trigger the MSO on logic patterns and analog characteristics or a combination of both. You can then use software options that include Search and Mark that let you trigger the instrument and mark an area of interest for finding signals within long record lengths. Other software options include DDR analysis for debugging computer memory.<> You can also add more than 30 other software options, including jitter analysis, power analysis, communications tests, and serial data debug.
Base prices: 4-GHz model-$67,400; 20-GHz model-$174,000. Probes and software are optional.
