Adjust the laser current with the potentiometer (highlighted in blue).
Laser current is limited at 56 mA and can be monitored at the IMON pin (33.2 mV/mA).
Modulate the laser using the bias-tee input available on the Mod. in SMA connector.
The modulation input is AC-coupled with a cut-off frequency of 1.6 kHz.
Modulation gain is 20 mA/V above 1 MHz.
The output of the integrated photodiode is available on the PD out SMA.
The transfer function is Vout = 0.6 V - 510 * Iout is the photodiode current.
