High Performance Mixed Signal Oscilloscope

High Performance Mixed Signal Oscilloscope

   

The expanded Infiniium 90000 X-Series oscilloscope family from Agilent Technologies Inc. includes the world's highest performance mixed-signal oscilloscope, or MSO. The expansion adds six new MSO models, as well as 13-GHz DSO and DSA models, to the X-Series. Engineers and developers use MSOs to accelerate testing by employing the additional trigger flexibility for debugging and validating their devices.

The tightly integrated digital channels of the new MSO models can function at 20 GSa/s in an eight-channel configuration, 60 percent faster than other high-performance MSOs, or at 10 GSa/s in a 16-channel configuration. Agilent now offers MSOs ranging from 70 MHz to 33 GHz of analog bandwidth. The new 13-GHz DSO, DSA and MSO models give engineers access to the industry's lowest noise and jitter measurement floors of the Infiniium 90000 X-Series at an unprecedented low price.

With the Agilent Infiniium 90000 X-Series, current and future customers who purchase DSO or DSA model oscilloscopes can upgrade to MSO functionality. Most high-speed MSOs available today come with fixed configurations that cannot be upgraded. Agilent's N2834A upgrades let users add MSO capability at any time. This capability, along with Agilent's existing bandwidth and memory upgrades, makes the X-Series one of the most flexible and expandable platforms on the market.

Unlike other MSOs, Agilent Infiniium 90000 X-Series MSOs have up to 400 million points of data capture behind each digital channel. To accommodate sample-rate differences between the high-speed analog channels and the digital MSO channels, this memory depth can be automatically sized with the analog trace length, including the full 2-Gpts memory available on Agilent oscilloscopes. This memory depth allows for fully time-correlated capture of elusive events that span a long time record.

Very fast memory channels, such as DDR3, often have complex signal qualification conditions that can elude even the most adept engineer. Agilent has added a special DDR triggering mode to the new MSOs to perform read/write separation and eye alignment for these complex conditions.

Protocol errors plague even the most mature system designs. While some modern scopes have the ability to move up the protocol stack on the analog channels, an engineer trying to understand root cause can quickly use up the scope's analog channels. Adding an MSO makes up to 16 high-speed digital channels available for the measurement. Protocol checking on the digital channels for a measurement like DDR makes it possible to see the full view of analog impacts while validating protocol compliance.
