ownership leadership 6 GHz, 20 GSa/s
When you choose your next oscilloscope, bandwidth is the most
important specification to consider, as it defines the maximum
frequency content your oscilloscope can acquire. Acquiring
signals with faster edge rates or faster fundamental frequencies
requires higher-bandwidth scopes to make the most accurate
measurements. However, the higher the bandwidth of your
oscilloscope, the higher the price is likely to be.
Sample rate is the second important specification, as it
determines the time span between each acquired sample point,
and it ultimately becomes the limiting factor of the oscilloscope’s
Figure 2. An oscilloscope with 1.5-GHz bandwidth captures only the
bandwidth. In a modern oscilloscope with Brickwall filter
response, the sample rate must be at least 2.5 times higher the
bandwidth. So a scope with 6-GHz bandwidth requires a sample
rate of at least 15 GSa/s to avoid aliasing.
fundamental frequency of a 2.5-Gbps PRBS signal.
With the InfiniiVision 6000 X-Series, you can get up to 6-GHz
bandwidth and a 20-GSa/s sampling rate so you can confidently
measure signals with rise times faster than 150 ps or signals with
higher than 2-Gbps NRZ (non-return to zero) data signal rates.
Explore Figures 1 through 4 to see the power extra bandwidth
delivers to your measurements.

harmonic of a 2.5-Gbps PRBS signal.

The rise time measurement by
– Channel 1 at 6-GHz bandwidth (yellow): 132 ps
– Reference 1 (R1) at 3-GHz bandwidth limit: 196 ps
– Reference 2 (R2) at 1.5-GHz bandwidth limit: 216 ps
Figure 4. An oscilloscope with 6-GHz bandwidth sees up to the 5th
harmonic of the 2.5-Gbps PRBS signal. You see the true signal integrity
of your waveform.
