2.2.2 Electrical System
Figure 2.6 shows the configuration of the electrical system used in the V-550, V-
560 and V-570. The light incident on the photomultiplier tube or Pbs
photoconductive cell is converted into an electrical signal and, after being
synchronously rectified, is converted
microcomputer. The signal processed by the microcomputer is displayed on the
output device as digital data or a spectrum.
Light source changeover, wavelength drive, slit drive, filter drive, etc. are
controlled by the microcomputer.
