CAMAC - 3518 16-bit, Scanning A/D Converter Host View Datasheet Request Ordering Information     ABOUT 3518 The Model 3518 is a single-width CAMAC module containing a high-resolution analogto- digital converter capable of resolving one part in 65,536 (16-bits).This module is used in conjunction with companion input conditioning modules(such as the Models 356404-channel Strain Gage w/Filter and 3565 8-channel RTDw/Filter) to form a signal-conditioned, scanning A/D subsystem. Up to 32 input channels are accommodated by the 3518. The number of active (scanned) channels is software programmable. The inputs are scanned, and the results are stored in a 32-word memory which can be read via the Dataway. There are two software-selectable scan modes, continuous and single-scan. With continuous mode, CAMAC Read cycles are asynchronous with the conversion process, eliminating any overhead due to testing for a converter busy. If it is desirable to synchronize scanning and reading, the single-scan mode is used. In this mode, a LAM status is set after the last channel has been converted. In addition, external triggering may be used to synchronously trigger a singlescan on multiple 3518s. The 3518 contains a 4-bit, 32-word memory which can be loaded on a channel-bychannel basis from the Dataway with an appropriate gain factor applied to each differential input signal. Eleven gain factors, from one to 1024, are available in a binary progression. This allows one 3518 to measure a wide variety of input signal types (such as thermocouples, RTDs, high-level inputs).
