Measurement Uncertainty
The measurement uncertainly is up to double the amplitude
measurement accuracy of the measuring instrument. When a value of
which the measurement uncertainly is added or subtracted to/from the
measurement value is in the range of the specifications, the value passes.
The measurement uncertainty of the frequency accuracy when using
MF2412C Microwave Frequency Counter as the frequency counter is
shown below.
Without MF2412C-003: 0.1 ppm
With MF2412C-003: 0.01 ppm
Refer to Amplitude accuracy in Table A.3.9-2 “Electrical Channel
Performance” for the amplitude measurement uncertainty when using
MP2110A as the sampling oscilloscope. Examples of calculating the
amplitude measurement uncertainty are listed below.
