Use AMPCOR to compensate for wavelength-dependent amplitude variations at the input port. Pairs of wavelength-amplitude correction points can be entered, depending on the availability of adequate internal memory. The wavelength values entered must be equal or be in increasing order, or an error condition results. Whenever AMPCOR is on, the correction values are added to all measurement results.

The values of the correction points are applied across the active measurement range. Between points, the correction values are interpolated. When measuring at wavelengths outside the ￿rst and last correction points, the ￿rst or last value (as appropriate) is used as the correction value.

When AMPCOR is executed, the wavelength-amplitude pairs are stored in internal memory. DISPOSE ALL, FORMAT, and PERASE erase the amplitude-correction pairs from memory.

Queried values are 0, 0 when AMPCOR is set to OFF.
