A controller performing a fast analog-to-digital conversion of electric signals (7-bit output), their recording into the random-access memory (RAM), and transfer of the digital data to the ISA bus (IBM PC) is developed. Rectangular pulses with programmable duration and pulse period-to-pulse duration ratio are generated for their use as probing and synchronizing ones, as well as for the formation of pulse trains. The controller is a normalized module inserted directly into a slot of the ISA bus.
