LBAL AND ILOS TESTS
The accuracy is given as:
where
A
T
is the total accuracy (dB)
A
R
is the basic relative accuracy (dB)
A
C
is the correction for calibration
A
VI
is the correction for the input voltage level
A
VO
is the correction for the output voltage level
The value of A
R
is given in the table in section 1.1 of this chapter.
The values of the other factors are given below.
where
F
M
is the measurement frequency (Hz)
V
MI
is the measured input voltage (V)
V
MO
is the measured output voltage (V)
