At the same time the receiver excludes most of the light from the background. The pulse rate is pro- portional to the amount of light falling on the receiver. (See fig. 5-15.) The AMPLIFIER-POWER SUPPLY unitpro- vides regulated voltage for the photoelectric receiver and amplifies the pulse signal of the receiver for transmission to the indicator. A metering unit is also provided to facilitate field adjustment. The INDICATOR is essentially a frequency meter which converts the pulse signal to a direct current which is proportional to the pulse rate and hence to the transmission. The RECORDER provides upon a strip chart a continuous record of the output of the indicator. An auxiliary pen indicates the sensitivity range on which the indicator is operating. In all models of Transmissometer AN/GMQ- 10( ), the Indicator and recorder are housed in a single unit, which is known as the indicator- recorder. The CABLE TERMINAL CHAMBERS, of which there are two with each set, act as a housing and a junction for all cabling used in the set. One cable terminal chamber is mounted on the projector stand, and the other is mounted on the receiver Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Naval Education and Training Program Development Center; United States.
