ATML Use cases
Use of ATML by external agencies is gathering
momentum

Agilent Instrument Database
Performing an independent evaluation into using the
ATML instrument description and ATML capability to
distribute their instrument information.
This is important because, if successful, there will be
a lot of information in the ATML format – that will
generate a lot of user based feed back on our trial use
standard(s)

Synthetic Instrument defined using ATML
Synthetic Instrument Working Group has defined a
general architecture for synthetic instruments.
Each component that makes up the synthetic
instrument needs both software and hardware
interchangability.
ATML Instrument Description has been chosen as the
format to represent the description of the hardware
specifications for the following components:
 Arbitrary Waveform Generator
 Digitizer
 Down Converter
 Up Converter
IVI Drivers have been selected for the software driver
interchange format.

MoD Open System Architecture Approach
The MoD currently have a policy for ATS to use the
IEEE 1641 ‘signal modelling’ standard.
Looking to standardise a common Open System
Architecture approach
This process is expected to make heavy use of the
ATML standards
Framework Working Group 2007

Proposed Common OSA Standards
High degree of obsolescence coupled with a lack of commonality has resulted in:
High in-service support costs
Relatively low utilisation of test platforms
A common open standard is therefore vital to overcome these concerns. This must be
encompassed within the common GPATE with the technology to achieve this capability.

REQUIRED Common Use Standard Signal Library
TSF Development
We need to develop standard Signal libraries to capture the test
domain knowledge of what signals are required.
 CASS ATLAS Signal Library
Already modelled certain signals and measurements in 1641
(but never completed as TSFs)
 SIWG measurement science & ‘signals’ methods
 ARGCS ATLAS Signal Libraries
Train users in using the common signal libraries in their field of
operation rather than the user needing to know how specific
signal are implemented.
 TPS projects and field test engineers would then use these TSF signal
definitions as reusable components, rather than continually build there
own up from scratch
Provide a solid foundation for a standard common use signal
library
 Ability to use additional interchangeable Signal Libraries though TSFs
 New TSFs can be added into the standard at subsequent revisions

Signal Modelling and the Framework
The term signal modeling is simply defining signals through models.
 A signal model includes signal sources, signal conditioning, signal based
measurement, digital, communications & busses, events, timing and even
locations or combination of them.
The model is an executable specification that provide a means to define
both behavior and interface parameters, and utilize both composition
and hierarchy to allow building increasingly complex signal definitions,
as reusable components
 Regardless of the complexity of the signal, because they define behavior, signal
models represent an ideal component of test requirement interchange.
Signal modeling can have a positive impact on several DoD (and MoD)
objectives

