Abstract: Device for synchronous modulation, synchronous light-path switch-over and control-signal derivation for step-drive controlled modulation and switch-over devices, especially for multibeam spectral analysis equipment and preferably for the infrared region of the spectrum, in which the radiation modulation is effected by a rotating light stop and the light path switch-over between a measuring beam and a reference beam is effected by pivoting mirrors. The device provides for the use of only a single photosensor. The synchronization between the stepping motor for moving the light stop and the stepping motors for moving the mirrors is effected via a counting logic and common clocking. Moreover, set pulses are generated to set the mirrors in defined positions, and control signals are generated for further processing.
