LSI-11 Analog System User's Guide

This document is the LSI-11 Analog System User's Guide, published by Digital Equipment Corporation. It provides comprehensive information for users of Digital's dual-height analog I/O printed circuit board options for the LSI-11 processor.

The guide covers:

• Introduction: An overview of the analog boards, which typically form an analog I/O system.
• ADV11-C Analog Input Board: Details its features (16 single-ended or 8 differential inputs, programmable gain, 12-bit resolution, various data notations), functional description, programming instructions for its registers, and configuration data (device/interrupt addresses, input range, type, polarity).
• AAV11-C Analog Output Board: Describes its four digital-to-analog converters (DACs) with 12-bit input resolution, unipolar/bipolar output options, voltage range selection, and a 4-bit digital output for control signals. It also includes programming and configuration details.
• AXV11-C Analog Input/Output Board: Combines functionalities of both input and output boards, offering 16 single-ended or 8 differential analog inputs (with programmable gain and 12-bit resolution) and two DACs for analog output. Programming, configuration, and interfacing information are provided.
• KWV11-C Programmable Real-Time Clock: Explains this board's role in timing A/D conversions using a crystal oscillator, line frequency, or external triggers. It features two Schmitt triggers for event detection and offers four programmable counter modes.
• Calibration and Testing: Provides procedures for calibrating and testing the analog boards, including the use of an optional analog test fixture and diagnostic software.
• Glossary: Defines technical terms related to analog-to-digital conversion.

The manual aims to enable users to understand, program, configure, and calibrate these LSI-11 analog system modules for various applications.
