LT{sp}[1,2,A]{cr}
Example usage:
LT{sp}1{cr}
Requests TEC temperature of pump laser 1
Reply is in the form:
LASER1:{sp}25.5{sp}C{cr}
Signifying that the pump laser 1 has a temperature of 25.5 C.
Example usage:
LT{sp}A{cr}
Requests TEC temperature of all pump laser.
Reply is in the form:
ALL:{sp}25.2{sp}25.0{sp}C{cr}
The range for the TEC temperature is: 15.0 C to 35.0 C.

PH{cr}
Reply is in the form shown, where PDM1 is the input power stage 1, PDM2 is
the output power stage 1 before the VOA, PDM3 is the input power stage 2,
PDM4 is the output power stage 2.
PDM1:{sp}-8.2{sp}dBm{cr}
PDM2:{sp}10.0{sp}dBm{cr}
PDM3:{sp}6.4{sp}dBm{cr}
PDM4:{sp}20.5{sp}dBm{cr}
TS{sp}[1,2]{sp}<value>{cr}
This command is used to set the TEC. The TEC temperature has a fixed value internally (say
25 C).
Example usage:
TS{sp}1{sp}25{cr}
Sets the operating set point to 25 C.
Reply is in the form:
TS{sp}1{sp}25{cr}
The TEC temperature has a settable value. An error will be generated if the
settable value is below the minimum temperature and if the settable value is
above the maximum temperature. Available on prototypes and series.
The range for the TEC temperature is: 15.0 C to 35.0 C.
