The optional chopper box TicChop is designed for direct modulation of the bias voltage of a Toptica photo-emitter. Connect the input of the chopper box to the camera's chopper port with the included chopper cable. Use a regular SMA cable to connect the SMA output connector to the photo-emitter bias port. Ensure that the voltage levels of the chopper box (on at -1.5V and off at +0.5V) are compatible with the specifications of the photo-emitter to ensure proper functionality and to avoid any damage. See the wiring diagram in the appendix.

Specifications are subject to change without prior notice.
