This function allows adjustment of the optical axis of the instrument’s built-in monochromator (spectroscope). The instrument’s optical performance is not guaranteed until the alignment adjustment function has been executed. Failure to perform this adjustment can result in distortion of measured waveforms. After alignment adjustment has been executed, wavelength calibration is also subsequently performed automatically. If you are using the instrument for the first time or using it after it has been severely shaken while being moved, perform the alignment adjustment procedure after warm-up ends. Wavelength Calibration > Wavelength calibration can be performed using the internal reference light source (when the built-in light source specification is -L1) or an external light source. Resolution Calibration > Typically the filter response of an optical spectrum analyzer is not rectangular, and thus the resolution bandwidth differs slightly from the equivalent noise bandwidth. This difference becomes prominent especially when the wavelength resolution is high (e.g., 0.05 nm or less). The resolution calibration function measures the equivalent noise bandwidth at each resolution setting and internally sets the resolution bandwidth to the result. The resolution bandwidth appears in parentheses in each of the resolution soft keys on the resolution screen. The resolution bandwidth accuracy affects the results of noise measurements and the results of optical power measurements of wideband light sources. In detail, the resolution bandwidth is used when the following analysis and computation functions are executed. For details, see pages 3-25 and 3-26.
