IEEE 488 Interface

Informacja

The Model 1973 is an IEEE-488 Interface for the model 197 Autoranging Microvolt DMM. This Interface adds extra versatility to the model 197 by allowing the transmission of data and commands over the IEEE-488 bus. The Interface provides all the necessary logic to Interface the model 197 to the bus using standard IEEE-488-1973 protocol. The Model 1972 is an IEEE-488 Interface that is very similar to the Model 1973, In fact, the only difference between the two interfaces is that the Model 1972 includes an Analog Output and the Model 1973 does not. Since the only difference between the two Interface is the analog output, the Model 1973 is referred to throughout the manual. Section 5 and 6 contain information concerning the analog output of the Model 1972, All the rest of the information pertaining the Model 1973 also relates the Model 1972, The analog output specifications precede the Table of Contents. The Model 1973 1972/IEEE-488 Instruction Manual covers the following IEEE 488 Interface options: • Model 1973 IEEE-488 Interface (for the model 197) • Model 1973A IEEE-488 Interface (for the Model(197A) • Model 1972 IEEE-488 Interface (for the model 197) • Model 1972A IEEE-488 Interface (for the Model(197A)
