The display is divided into three equal rows. Each row shows measurements for
each wavelenght. Next are described each one of the fields on screen:
[1] Wavelenght at which it is measuring.
[2] Absolute optical power of the signal at the corresponding wavelenght.
Absolute measurement mode is the absolute power of signal in dBm (dB
referred to 1mW).
[3] Absolute signal losses (Attenuation) at the corresponding wavelenght. It
represents the losses power of the signal in dB.
[4] Relative losses of the signal with respect to the reference value. Reference
value can be changed by capturing a new one.
[5] Group of threshold values selected. Threshold values can be grouped and
saved on the memory of the instrument and later to select the one that best
meets the criterion of quality to follow.
[6] Upper threshold value.
[7] Power graphical representation.
[8] Lower threshold value.
[9] Signal status with respect to threshold values. Three status are possible:
PASS, HIGH, LOW.
