Description
The sin(x)/x bandwidth can be solved for using the following equation:
20 * log (sin(x)/x) = -3
For interleaved waveforms: x = 2π * fout ÷ fsample
For non-interleaved waveforms: x = π * fout ÷ fsample
fsample = sample rate
fout = sin(x)/x bandwidth
≤ 25 GS/s (non-interleaved): 11.1 GHz * fsample ÷ 25 GS/s
> 25 GS/s (interleaved): 11.1 GHz * fsample ÷ 50 GS/s
11.1 GHz * fsample ÷ 25 GS/s
Analog bandwidth is measured with the ideal sin(x)/x response curve of the DAC
mathematically removed from the measured data.
15 GHz at 50 GS/s
13.5 GHz at 25 GS/s
When operating in interleaved mode, rising and falling edges are created using two sample
points. As a result, the rise/fall time is dependent on the sample rate.
≤ 25 GS/s: < 23 ps
at 30 GS/s: < 42 ps
at 40 GS/s: < 32 ps
