-(Minus) indicates that current is being injected into LD.
1 indicated that coherence control is now on.
1 indicates that ne tuning control is now on. 2 indicates that frequency
locking is on.
1 indicates that ACC mode is now on. 2 indicates that automatic ATT mode
is now on. 3 indicates that both ACC and ATT are operating.
1 indicates that the actual temperature of the LD block and/or the optical
unit is greater than ±0.1°C from the target temperature. 2 indicates that the
actual etalon temperature of the frequency locking unit is greater than ±0.1
°C from the target temperature. 3 indicated that both LD block and/or opti-
cal unit and etalon temperature are out of target range.
1 indicates that the LD current driver has reached its hard limit.
1 indicates that wavelength tuning is on. 2 indicated that set current value
for current driver tuning is now on. 4 indicates that ATT tuning is on. The
displayed value is a summed combination of the above conditions.
1. Attenuation tuning is on.
2. Injection current is within the control range.
3. Temperature is stable.
4. APC mode is set automatic ATT control is operating.
5. Normal wavelength control status.
6. Coherence control is OFF.
7. Current is being injected into LD.
1. Attenuation tuning and wavelength tuning are on.
2. Injection current is within the control range.
3. Temperature is stable.
4. ACC mode
5. Normal wavelength control.
6. Coherence control is now ON.
7. Current is being injected into LD.
