Characteristics Description
Random Measurement
Uncertainty
(FCA3000, FCA3100,
MCA3000, channels A
and B)
For measurement time ≥200 ms and Smart Freq = Auto or ON:
NOTE. This equation is the default o n FCA3100 Series.
Where:
MR = M easurement reading
QE = Quantization Error
TE = Trigger Error
MT = Measurement Time
N = 800/MT with the following limits: 6 ≤ N ≤ 1000 and N<((MR/2)*MT) – 2
For FCA3100, additionally, N < MT/8 μs
For measurement time <200 ms and Smart Freq = Auto or OFF:
Where:
MR = M easurement reading
QE = Quantization Error
TE = Trigger Error
MT = Measurement Time
Systemic Measurement
Uncertainty
(FCA3000, FCA3100,
MCA3000 channels A and B)
Where:
TBE = Timebase Error
MR = Measurement Reading
MT = Measurement Time
GTU = Gate Time Uncertainty
Ancillary Measurements Vmax, Vmin, V
p-p
Period
Capable of measuring period on any of up to three inputs
