Can I use a PLCS-21 pulse generator for a driver with an analog signal input such as a LDP-VRM 01-12 CA?

The PLCS-21 is a digital pulse generator and only generates a 5 V high signal apart from its 0 V low state.
Thus, the PLCS-21 is not suitable for drivers with an analog signal input as only these two values are possible and also its precision is limited as only these two states need to be differentiated.

For drivers which require an analog input signal PicoLAS offers the PLCS-40. The PLCS-40 is an arbitrary pulse generator (pulsed-AWG) with an internal memory which can store up to 32 freely programmable curve shapes with a maximum duration of 320 ns.
