3.6 COUNTER-BASED SYSTEMS. A typical counter-based system (Figure 3-3) contains the
following electronic equipment:
One system controller (calculator or mini-computer).
One 5501A Laser Transducer.
Two 10780A Receivers.
One 10740A Coupler.
Two 10760A Counters.
A system controller interface (typically a 10746A Binary Interface; however a 10745A
HP-IB Interface can be used).
One 10755A Compensation Interface.
One 10756A Manual Compensator.
Two power supplies (k15V and +5V).
Additional capability can be selected by adding the following equipment:
a. Up to two additional measurement axes (10760A Counter and 10780A Receiver).
b. Automatic compensation (replace 10756A manual compensator with the 5510A Opt 010
Automatic Compensator and 10563A Material Temperature Sensor).
c. Numeric displays (10783A can be used only if the system controller is HP-IB compatible).

Counter-Based Computer Interface Electronics Block Diagram
This interface is used where high-speed position input to a computer based control system i s
desired. Since the output format can be either 8- or 16-bit words, the computer interface
electronics are compatible with almost any digital processor. Refer to Table 3-2 for typical
specifications.
