Stability spec based on a 1 hour warm up period.
4
The maximum USB and BNC cable length is 3 meters in order to avoid a susceptibility to RF interference according to IEC61000-4-3.
5
Modulation Input voltage directly corresponds to output power, where 5V = Max power and 0 V = Min power. See section 5.9; Modulating the Laser Output.
6
Assuming sine wave modulation. For modulation other than a sine wave, consider the bandwidth as a function of the rise time. See
section 5.9; Modulating the Laser Output.
7
This laser source may experience mode-hopping that can’t be tuned out with temperature or current adjustment. Therefore, power stability should be interpreted
as the maximum power drift over that period.
