Diagram
The voltage input through the connector is converted, in differential and
range circuits, to a voltage proportional to the input voltage, and transferred
to the 3194 proper by an A/D converter.
When measuring a rotation rate by counting pulses, channel B can be
switched so that pulses are counted by the frequency measurement function
in the 3194 proper.
