The highest-performance end-to-end measurement system available

If you are an experienced scope user, you know that your measurements are only as good as your probing system. And as bandwidth increases, it’s increasingly important to ask the question: am I measuring my circuit or my scope probe? Nothing is more frustrating than chasing down an apparent design problem, only to find that it was caused by an inferior scope probe.

Together, the newest Agilent Infiniium scopes and the breakthrough Agilent InfiniiMax

Key trends in the electronics market

• Technologies with dramatically increased clock speeds and edge rates have emerged.

• Very fast serial differential buses are being used to save board space, reduce power and provide better noise immunity.

• Densely packed circuit boards, often with stacked daughter boards, increase the need to probe in very hard-to-reach places.

How much bandwidth and sample rate do I need?

Bandwidth required to measure risetime with 3% error Example: 100 ps rise time (20-80%)

Maximum signal frequency content = 0.4/rise time (20-80%) Maximum signal frequency = 4 GHz

Scope bandwidth required = 1.4 x maximum frequency Required scope bandwidth = 5.6 GHz

Minimum scope sample rate required = 2.5 x bandwidth Required scope sample rate = 14 GSa/s

Key benefits of the 54850 and InfiniiMax Series

• Up to 6 GHz bandwidth can track even the fastest signal speeds.

• A sample rate of 20 GSa/s on all four channels can measure high-speed differential buses correlated with other signals.

• The innovative InfiniiMax probing system supports even the most demanding mechanical access requirements without sacrificing performance.

20 GSa/s Sample Rate on All Channels at Once!

• The full real-time bandwidth of up to 6 GHz is supported on every channel by the 20 GSa/s sample rate.

• This industry-leading sample rate produces more accurate and repeatable measurements, avoiding measurement error and signal aliasing due to under sampling, as shown above.

• The combination of 6 GHz bandwidth and 20 GSa/s sample rate on all channels makes the 54850 series ideal for designs that include: PCI-Express, Serial ATA, Rapid IO, HyperTransport, InfiniBand, or Gigabit Ethernet.

20 GSa/s provides accurate measurement.

10 GSa/s is not enough.

5 GSa/s is not enough.

Sample rate Measured rise time

20 GSa/s 89 psec

10 GSa/s 137 psec

5 GSa/s 238 psec

Example for 90 ps rise time input

Easy-to-understand, easy-to-use jitter analysis

Includes the following key measurements: cycle-to-cycle jitter, n-cycle jitter, period jitter, time interval error, setup and hold time, measurement histograms, measurement trending, and jitter spectrum.

The jitter setup wizard

Guides you through the setup of the jitter measurement, describes what the measurement does and tells you when to use it.

Application Software

Infiniium: “It’s like someone who sits down and actually uses a scope designed this one.”

Steve Montgomery, Director of Engineering, Linx Technologies
