Accuracy
The formula to calculate delta-time measurement accuracy (DTA) for a given instrument setting and input
signal is given below (assumes insignificant signal content above Nyquist)

(1

point in the m easurement
SR
2
=SlewRate(2
nd
Edge) around the 2
nd
point in the m easurement
N = input-referred noise (volts
rms
, Refer to the Random Noise, Sample acquisition mode specification)
t
sr
=1/(Samp
le Rate)
TBA = timebase accuracy (Refer to the Long-term sample rate and delay time accuracy specifi cation)
t
p
= delta-time measurement duration (sec)
RD = (R ecord
Length) / (Sample Rate)
Assumes that error due to aliasing is insignificant.
The term under the square-root sign is the stability, and is due to TIE (Time Interval Error). The errors due
to this term occur throughout a single-shot measurement. The second term is due to both the absolute
center-frequency accuracy and the center-frequency stability of the timebase and varies between multiple
single-shot measurements over the observation interval (the amount of time from the first single-shot
measurement to the final single-shot measurement).
