4.2.3 ATTENUATION TEST Function
This function measures simultaneously and selectively the signals emitted by a
test source (PROLITE-105) in three wavelengths thanks to the selective filters existing
on each band. These data are essential to certificate a fibre optic installation. The
program supplied with the instrument generates a certificate from the data recorded.
To access this function:
1.-

Press SEL
To make a proper measurement with this function, first you have to capture the
reference values. To do this you should use the PROLITE-67 with a calibrated
wavelenght generator (PROLITE-105) working in simultaneous mode with these 3
wavelengths working at the same time through a reference optical fibre. Then you have
to capture the new reference values pressing UP
simultaneously for one second. Now you can make measurements on the optical fibre
at the installation. For a practical application refer to the appendix.
