Calibration of the Agilent 81001FF Attenuation Filter

NOTE 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.

2 Set the power meter installed in the HP 8153A to the following

values:

a Set range to 0 dBm; press Up or Down as required.

b Set T, the averaging time, to 500 ms.

c Agilent 81680A, 40A, 82A, 42A, & 89A:

Set λ, the wavelength, to 1550 nm.

Agilent 81480A:

Set λ, the wavelength, to 1450 nm.

d Select dBm as the power units.

3 Move to the Tunable Laser channel of the Agilent 8164A.

Agilent 81680A, 40A, 82A, 42A, & 89A:

Set λ, the wavelength, to 1550 nm, and [P], the power, to 0 dBm..

For Agilent 81480A:

Set λ, the wavelength, to 1450 nm, and [P], the power, to 0 dBm.

4 Press the key beside the laser output to switch the laser on.
