4.4.4 Measurement connection
These connections give acc e ss to the voltage on the
laser.
The ”L” connection is connected AC coupled to
the cathode of the laser through a divider by ten.
The end of cable must be 50Ω terminated for accu-
rate measurement. The ”B” is connected the same
to the anode of the laser (Bas e Receptacle).
By using the math trace of an oscilloscope s how-
ing the ”L” channel minus the ”B”, one can get the
voltage on the laser.
This measurement is more accurate than the in-
formation obtained from the LDD100 measurement
unit.
For more details, refer to LDD100 Diagram Block
on page ??.
