Understanding IEEE 1641—Essentials of Measurement
A discussion on how to use the measurement capability in IEEE 1641. 1641 supports two different
types of measurement; intrinsic and generic. This application note explains each type and what
they mean. The explanation of each type includes examples together with brief explanations of the
main points.
Understanding IEEE 1641—Using Loads
A discussion on how loads and impedances are represented in IEEE 1641. There are two completely
different kinds of load within IEEE 1641. One is a BSC and the other is a property of the Physical class.
In addition, 1641 may be used to define a signal of type Impedance, which adds a third possibility when a
load is required. This application note explains each kind and when they should be used.
Understanding IEEE 1641—Signals & Triggering
This application note explains how to describe a signal that is being triggered by another signal.
The problem is illustrated by an example in which concern was expressed about the test description being
linked to a specific implementation. The example is described using the IEEE 1641 standard and shows how
the problem is expressed without demanding any particular implementation.
Understanding IEEE 1641—Implementing Synchros
This application note describes how to define signals and measurements in IEEE 1641 that involve the use of Synchros and Resolvers.
The examples include various IEEE 1641 models of a synchro; as source TSFs and as transformation TSFs.
Also included is an explanation of why generic measurement is particularly suited to synchros and resolvers.
Simulated signals are also provided to show the effect of both stationary and moving rotors.
