Multi-channel acquisition control box of novel light polarization system

A multichannel acquisition control box of a novel optical polarization system comprises a power supply module, a driving module, an acquisition module and a signal conversion module. The data acquisition module comprises an analog signal reference wiring port, an analog quantity input port, an analog signal grounding port, a digital signal grounding port, a timer clock source input port, a digital trigger signal input port, an off-board clock input port and an in-board clock input port; the driving module comprises a 12v power supply port, a four-phase stepping motor port, a pulse input port, a direction control port, an enabling control port, a grounding port and a 5v power supply port; the signal processing module comprises a power supply port, an optical signal output port, an analog signal output port, a grounding port and a 12v power supply port. The multichannel acquisition control box can more vividly display the functions of each module, and deepen the understanding of students on the experiment princ
