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.
