220.127.116.11 LBAL and ILOS Tests
The accuracy is given as:
AT = AR +0.87 ( AC+AVI+AVO)
AT is the total accuracy (dB)
AR is the basic relative accuracy (dB)
AC is the correction for calibration
AVI is the correction for the input voltage level
AVO is the correction for the output voltage level
The value of AR is given in the table in section 1.1 of this chapter.
The values of the other factors are given below.
AC = 0.1 + (0.0000001% x FM )
AVI = 0.001 / VMI
AVO = 0.001 / VMO
FM is the measurement frequency (Hz)
VMI is the measured input voltage (V)
VMO is the measured output voltage (V)
