Optimize Optical Modulator Bias

Allows manual activation of the procedure to find the optimum
modulator bias, performed at the center of the current
measurement wavelength range. During normal measurement
procedures, this is activated automatically as needed during
normalization measurements. Manual activation can be used for
diagnostic purposes, especially if the setup seems to deliver
insufficient optical power. In that case, this optimization can be
applied before using the Real-Time Port Monitor. Manual use
will cause the current normalization measurement to become
invalid. (A normalization measurement can be saved to reload
after testing the change of parameters.)
