Total:
<250 fs rms for record durations less than 10 μs
<350 fs rms for record durations less than 100 μs
<650 fs rms for record durations less than 1 ms
<15 parts/trillion for record durations less than 60 s
<2 ps peak-to-peak for record durations less than 10 μs
<3 ps peak-to-peak for record durations less than 100 μs
<4 ps peak-to-peak for record durations less than 1 ms
This assumes either internal reference, or external reference in low (stable) mode. For external
reference in high (tracking) mode, the input reference must be low noise, and the edge slew
rate must exceed 1.5 V /ns to achieve the above approximate jitter results. For the general
case, external reference in high (tracking) mode, the specification is:
<250 fs rms for record durations less than 2 μs
You can approach the performance of internal reference using a clean reference signal with
input slew rate exceeding 1.5 V/ns. This is most easily achieved either with a square wave
meeting that slew rate or using a 100 MHz sine wave (≈2V
p-p
). This is required for the best
possible performance in synchronous sampling applications.
<4 GHz models
Total:
<1 ps rms for record durations less than 10 μs.
<2.5 ps rms for record durations less than 30 ms.
<65 parts/trillion for record durations less than 10 s.
