26 Agilent 81618A/9A and Agilent 81623B/4B/6B/8B Optical Heads, Fourth Edition

Power range

The power range is defined from the highest specified input power level to

the smallest input power level that causes a noticeable change of

displayed power level.

Conditions: wavelength, averaging time as specified.

Wavelength range

The range of wavelengths for which the power meter is calibrated.

Note: Selectable wavelength setting of the power meter for useful power

measurements (operating wavelength range).

Relative uncertainty (spectral ripple) due to

interference

Uncertainty of power reading when using a coherent source, due to a

periodic change of the power meter's responsivity caused by optical

interference between reflective interfaces within the power meter's

optical assembly.

Conditions: constant wavelength, constant power level, angled connector

as specified, linewidth of source <100 MHz, temperature as specified.

Spectral ripple is measured by stepping the source wavelength over the

wavelength range specified.
