Tektronix DPO5000 Series Technical Reference

<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.
Jitter noise floor, typical, ≥4 GHz
models
Applies to time periods as long as 10.0 μs. Typical jitter noise floor is measured at the maximum,
BWE enabled bandwidth:

Calculate the jitter noise floor (JNF) for a given instrument setting using the following formula:
Ntyp = typical input-referred noise spec (volts rms)
FN = 1.3 for instrument bandwidth ≤9 GHz; 1.5 for instrument bandwidth ≥10 GHz
SR = slew rate around the measurement
FI = (1.7 x 10–2)/sqrt(2) = 1.2 x 10–2
tr = rise time of the measurement edge
tj = timebase jitter or aperture uncertainty
TBA = timebase accuracy (2 ppm)

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
trm = 10 - 90% displayed (or measured) rise time (seconds)
N = input-referred noise (volts rms)
tj = short term timing jitter (seconds rms)
