Calculate the jitter noise floor (JNF) for a given instrument setting using the following formula:
FS = full-scale setting (volts)
A = signal amplitude as a fraction of full-scale
t = 10 - 90% displayed (or measured) rise time (seconds)
rm
N = input-referred noise (volts rms)
t = short term aperture uncertainty (seconds rms)

Total:
<1.0 ps rms for record durations less than 10 μs
<2.5 ps rms for record durations less than 30 ms
