Abstract (en)
[origin: WO8707054A1] Universal programmable modules provide timing and/or address register functions for a broad family of test instruments; such as counter timers, arbitrary function generators, and real time digitizers. The computer programmable apparatus (20) can be used as an accumulator, a time base generator or a memory address register. A clock input (50) receives a clock input signal. A computer input (32), which may include a bidirectional data bus (30), receives inputs from a computer. A processor (24) processes at least one of the clock input signal and the input from the computer to produce at least one output (56, 58, 78). A control circuit (50) controls the processor in accordance with further input from the computer to determine the output produced. An output selector (28), which may include a multiplexer (40) for directly addressing memory, selects at least one output to be used externally of the apparatus.
