New Standard for Price Performance: Bandwidth, Visualization, and Integration

Bandwidth

Superior signal integrity with total-cost- of-

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

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.

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.

Figure 1. Measuring the rise time of a 130-ps rise-time edge (10 to 90%).

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 2. An oscilloscope with 1.5-GHz bandwidth captures only the

fundamental frequency of a 2.5-Gbps PRBS signal.

Figure 3. An oscilloscope with 3-GHz bandwidth sees some of the 3rd

harmonic of a 2.5-Gbps PRBS signal.

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.
