The Astronics/C&H Technologies MA209 is a 100 MHz pulse generator engineered for precision signal generation across research, development, and production test environments. Implemented as an M-Module conforming to ANSI/VITA 12-1996, it integrates with VXI, VME, PCI, and cPCI carrier boards. The MA209 delivers fully programmable frequency, pulse width, delay, and amplitude control with exceptional timing accuracy and flexible operational modes including single pulse, continuous, burst, and double-pulse generation.
