ABSTRACT

The A/D Converter Test for the 138E/139E and 189 converters is a set of routines designed for
maintenance personnel to aid in debugging hardware troubles, and as a periodic confidence check for data
flags,

interrupts, monotonicity, steady state accuracy, multiplexer selection and incrementation ability

of the multiplexer

REQUIREMENTS

3.1

Storage

The program uses memory 0 to 1500, and 6001

3.2

Subprograms and/or Subroutines (None)

3.3

Equipment

6100.

Standard PDP-8, Automatic A/D Converter Tester*,

39E, or the 189 A/D converter.

lieu of the

A/D converter 138E with or without multiautomatic tester, a high accuracy voltage standard

should be used for manual check out.

3.3.1

6032 KCC is used to clear the automatic tester.
6034 KRS is used to increment the automatic tester.

3.3.2
For automatic clearing and incrementing of the automatic tester, connections must be made
between IOT terminal points on the computer and connecting points on the automatic tester.
3.3.3

The digital-to-analog output of the automatic tester can be connected to the multiplexer input

or directly to the

A/D input.

USAGE

4.1

The program is in binary format. Load the program into core by following the instructions
published for the particular binary format loader being used.

Calling Sequence
If a voltage standard is being used in place of the automatic tester, use 660 as a starting adand the program comes to a normal halt. Then go to one of the following six starting addresses.

4.2.4
For initial start-up using the tester, use one of these six addresses; or use these addresses after
manual start-up is used.

Autoindex Registers 10 and 11 are used by the program.

Status of Core

The main program uses core in the area 0 to 1500 for program storage and core 6001 and 6100
as converted data storage

DESCRIPTION

6.1

Discussion
This package contains routines to aid the operator in troubleshooting the equipment, assuring

him of its correct operation. The nature of analog-to-digital converters precludes a completely automatic
diagnostic type of program. To this objective, the status printouts show:
1

Three stating conditions

Voltage states that are very narrow

Improper voltage limits

These checks are made by two tests: one checking steady state accuracy and the other checking monotonicity. A correlation should exist between printouts generated by these two tests to indicate a calibration
noise pickup
or a digital error. If a relationship cannot be found, this indicates the printouts were due to

and/or poor grounds.

Steady state accuracy is one way to measure the repeatability of the converter. If a voltage
going to an analog-to-digital converter remains constant, the converted digital value should maintain an
accuracy of ±1/2 LSB. This means that there may be two acceptable converted digital values for one

starting address.
