The C-995 phase-locked-loop optical chopper incorporates Direct Digital Synthesis in order to provide rock-solid, crystal controlled accuracy and stability. Its chopping frequency can be controlled to a precision of .001 Hz and has effectively zero frequency drift. A large, five digit LED display indicates the internally set chopping frequency, or in the External Sync mode, the measured frequency of the external clock signal.
