Optically isolated photodiode and modulation inputs mean no ground loops
Comes standard with both USB and RS-232 computer interfaces
Programmable PD bias
Constant voltage control mode
Plus all the safety features you'd expect from a next generation product, such
as hardware current and voltage limits, fast shutdown circuitry, and more.
