Wavelength	Range refers to the allowable wavelength range of the optical input signal.
	Absolute accuracy indicates the maximum wavelength error over the allowed
	environmental conditions. The wavelength accuracy is based on fundamental
	physical constants, which are absolute standards not requiring traceability to
	artifacts kept at national standards laboratories. Two He-Ne gas lasers are
	used. First, there is an internal 632.991 nm-vacuum (473.6127 THz) reference
	laser1. To verify absolute wavelength accuracy, an external laser is measured
	during manufacturing at 1523.488 nm, or 196.7804 THz2.
	Differential Accuracy indicates the maximum wavelength error in measuring
	the wavelength difference between two signals that are simultaneously
	present.
	Minimum Resolvable Separation indicates the minimum wavelength separa-
	tion of two laser lines required to measure each wavelength simultaneously.
	Two laser lines closer in wavelength than the minimum resolvable separation
	are not resolved and one average wavelength is displayed.
	Display Resolution indicates the minimum incremental change in displayed
	wavelength.
Amplitude	Calibration Accuracy indicates the maximum power calibration error at the
	specified wavelengths over the allowed environmental conditions. The ampli-
	tude calibration accuracy is traceable to a National Institute of Standards and
	Technology (NIST) calibrated optical power meter. NIST is the national stan-
	dards laboratory of the United States.
	Flatness refers to the maximum amplitude error in a measurement between
	two lines that are separated in wavelength by no more than the specified
	amount.
	Linearity indicates the maximum power error in measuring the change in power
