Timing jitter (aperture uncertainty),
typical
>20 GHz models
Measured at the maximum sample rate.
External Reference Low with ~0 dBm input drive at 10 MHz
<250 fs rms for record durations less than 10 μs
<350 fs rms for record durations less than 100 μs
<400 fs rms for record durations less than 10 ms
<600 fs rms for record durations less than 10 s
External Reference Hi with ~0 dBm input drive at 10 MHz
<250 fs rms for record durations less than 2 μs
<700 fs rms for record durations less than 10 s
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 typical jitter results.
Internal Reference
<250 fs rms for record durations less than 10 μs
<350 fs rms for record durations less than 100 μs
<400 fs rms for record durations less than 5 ms
In high (tracking) mode, the input reference must be low noise and the edge slew rate must
exceed 1.5 V/ns.
For internal reference, specification assumes no signal attached to the external reference input.
≥4 GHz, ≤20 GHz models
Measured at the maximum BWE enabled bandwidth.
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 (≈2 Vp-p). This is required for the best possible
performance in synchronous sampling applications.
