3 Preparation
Prior to start evaluation:
· Compare the pinning of your laser diode, that can be found on its data sheet, with the stand-
ard pin codes (see
· Choose the desired operating mode - Constant Power (CP) or Constant Current (CC)
Note
If you want to operate your laser in CP mode, it must have a built-in monitor diode.
Thus, the pin codes E, G and H are not supported by CP modules as these laser diodes
have no monitor diode.
· Select the evaluation adapter PCB:
o For CP mode, the selection of the appropriate adapter PCB depends on the pin code of
your laser - MLD203P1E (pin codes A, B or F) or MLD203P2E (pin codes C or D). then
continue with Operating a MLD203PxE Module (CP) on
o For CC mode, select the appropriate adapter PCB depending on your preferences regard-
ing low noise (MLD203CLNE) or high modulation bandwidth (MLD203CHBE). All pin
codes are supported. Then continue with Operating a MLD203CxxE Module (CC) on
