1. Introduction
Module A152 is a useful switching and Track&Hold mo-
dule. It combines three sub-units within one module:
• 1-to-8 multiplexer
• 8-fold Track&Hold
• 8-fold digital outputs unit
The active step of the three sub-units can be controlled
by an external control voltage (CV addressed mode)
or via a Clock/Reset controlled binary counter
(clocked mode). In this case the rising edge of each
clock signal causes an advance to the next step. The
rising edge of the reset signal resets to step 1.
The currently active step is displayed by a LED.
For the CV addressed mode a manual control and a
control voltage input with attenuator is available.
The module can be used for a lot of switching and
controlling functions in the A-100 system. Among other
things the T&H section of the A-152 allows the emulation
of the "toggling T&H" function of the Buchla module
