Calibration of the Agilent 81001FF Attenuation Filter
N O T E
When an HP 81524A Optical Head is used in conjunction with a
Agilent 81001FF Attenuation Filter, it is absolutely necessary that you
calibrate the Agilent 81001FF Attenuation Filter before starting the
power tests in the following measurement setups; it is not sufficient to
use calibration factors that are derived from an earlier setup.
1 Make sure all instruments have warmed up.
