See the attached wiring diagram for a typical connection of the TicCAM-1.1kpix camera together with a source array (TicSA-420G) or the chopper-box (TicChop) in conjunction with a Toptica THz photo-emitter. Note that the chopper connection is not needed in CW operation. For CW operation, disconnect any chopper cable and disable the EN-subtract option on the camera, then perform a zero with the source turned off.
