The
Subcommittee on Probe Standards (SCOPS) works under the Instrumentation and Measurement
Society Technical Committee TC-10, Waveform Measurement and Analysis. The goal
of SCOPS is to develop standards for characterizing the performance of
electrical circuit probes and probe systems, where these systems may include
waveform acquisition hardware and software and signal/waveform analysis
software, and the probe will include the mechanism by which the circuit is
contacted.
SCOPS is currently in the process of developing a standard for test methods and transfer (artifact) standards that will be used to characterize individual probes having one signal conductor and one ground conductor or two signal conductors, and having an input impedance greater than the impedance of the circuit under test. The scope of this standard, as stated in the Project Authorization Request is:
“This
standard provides test method(s) and describes transfer (artifact) standards
for characterizing electrical circuit probes and probes systems. The systems
may include waveform acquisition hardware and software and signal/waveform
analysis software. The probe will include the mechanism by which the circuit is
contacted. This method and standard will be applicable to all individual probes
having one signal conductor and one ground conductor or two signal conductors,
and having an input impedance greater than the impedance of the circuit under
test.”
The
present work is only considering voltage probes, including high-voltage
probes. Current and field probes
are not being considered at this time by may be the topic of future
standards. This work also includes
the analog portion of logic probes.
More
information on the purpose and need for this work is described in the Project
Authorization Request (PAR) form (see link below) for this project, P-1696 -
Standard for Terminology and Test Methods for Circuit Probes. Upon completion of this activity and
approval by the IEEE, a standard will be published.
The
present activity includes identifying relevant performance metrics and
developing associated test methods for probing systems. Details of our work done thus far can
be found in the “private area,” which requires membership to enter (see link
below).
SCOPS
is actively seeking new members.
Anyone who wishes to contribute to the development of the standard, such
as by contributing to the identification of performance metrics, drafting
descriptions of test methods, suggesting designs for artifact standards,
reviewing text and suggesting improvements, providing doughnuts at the
meetings, should contact the chairman at the link below.
