PAR Number Committee Title Scope
P287.1 IM/HFM - TC4 Standard for Precision Coaxial Connectors at RF, Microwave and Millimeter-wave Frequencies
The scope of this standard is to specify coaxial connectors for precision electrical measurements for use at RF, microwave and millimeter-wave frequencies.  Current state-of-the-art coaxial connectors are covered by the Standard.

This Recommended Practice provides supplementary information that enhances the user's knowledge, and promotes the proper use of precision coaxial connectors.  Included are the latest findings on effects encountered when mating precision coaxial connectors and tools that will give users the best methods for using and caring for precision coaxial connectors.
P378 IM/HFM - TC4 Recommended Practices for Scattering Parameter Measurements Using Vector Network Analyzers
Vector network analyzers are used to measure reflection and transmission coefficients of multi-port networks at radio, microwave and millimeter-wave frequencies from a few kHz to 145 GHz and beyond. This standard provides a common base for analysis of measurements made on vector network analyzers. A description of terminology is included so that a common language can be used to understand the measurement instruments and parameters, the methods of measurement, and the uncertainty associated with a measurement. Because of the complexities of the measurement parameters, instruments and uncertainties, this recommended practice does not cover all of the possible techniques and analysis method.
P1057 IM/WM&A - TC10 Standard for Digitizing Waveform Recorders
"This standard defines specifications and describes test methods for measuring the performance of electronic digitizing waveform recorders, waveform analyzers, and digitizing oscilloscopes with digital outputs. The standard is directed toward, but not restricted to, general-purpose waveform recorders and analyzers.
 
Special applications can require additional manufacturer information and verification tests not covered in this standard.
 
IEEE Std 1057(TM) has many similarities to IEEE Std 1241(TM)-2000 [B24],1 which applies to analog-to-digital converters (ADCs). However, IEEE Std 1057 shall be used for waveform recorders, and IEEE Std
1241-2000 shall be used for ADCs."
P1241 IM/WM&A - TC10 Standard for Terminology and Test Methods for Analog-to-Digital Converters
"The material presented in this standard is intended to provide common terminology and test methods for the testing and evaluation of analog-to-digital converters (ADCs). This standard considers only those ADCs whose output values have discrete values at discrete times, i.e., they are quantized and sampled. In general, this quantization is assumed to be nominally uniform (the input-output transfer curve is approximately a straight line) as discussed further in 1.3, and the sampling is assumed to be at a nominally uniform rate.
Some but not all of the test methods in this standard can be used for ADCs that are designed for nonuniform quantization."

The standard will define the protocol and interface. It will also define the format of the transducer TEDS. The transducer TEDS will be based on the IEEE 1451.2 TEDS. The standard will not specify the transducer design, signal conditioning, or the specific use of the TEDS.

P1451-99 IM/ST - TC9 Standard for Harmonization of Internet of Things (IoT) Devices and Systems
"This standard defines a method for data sharing, interoperability, and security of messages over a network, where sensors, actuators and other devices can interoperate, regardless of underlying communication technology. The backend of such a globally scalable, secure and interoperable network would be based on the eXtensible Messaging and Presence Protocol (XMPP), and rely on infrastructural components, or bridges, with standardized interfaces that provide real-time conversion of other IoT and M2M protocols, such as those based on CoAP (Constrained Application Protocol), HTTP (Hypertext Transfer Protocol), MQTT (Message Queuing Telemetry Transport Protocol), AMQP (Advanced Message Queuing Protocol), etc., and other interoperability interfaces, such as those provided by the IEEE 1451 Smart Transducer Interface, oneM2M, OMA LWM2M (Open Mobile Alliance Lightweight M2M), OIC (Open Internet Connection), UPnP (Universal Plug and Play), IPSO (Internet Protocol for Smart Objects) Alliance, etc.
 
The standard utilizes the advanced capabilities of the XMPP protocol, such as providing globally authenticated identities, authorization, presence, life cycle management, interoperable communication, IoT discovery and provisioning. Descriptive meta-data about devices and operations will provide sufficient information for infrastructural components, services and end-users to dynamically adapt to a changing environment. Key components and needs of a successful Smart City infrastructure will be identified and addressed. This standard does not develop Application Programming Interfaces (APIs) for existing IoT or legacy protocols."
P1588 IM/ST - TC9 Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems
"This standard defines a network protocol enabling accurate and precise synchronization of the real-time clocks of devices in networked distributed systems. The protocol is applicable to systems where devices communicate via networks, including Ethernet. The standard allows multicast communication, unicast communication or both. The standard specifies requirements for mapping the protocol to specific network implementations and defines such mappings, including User Datagram Protocol (UDP)/Internet Protocol (IP versions 4 and 6), and layer-2 IEEE 802.3 Ethernet.
 
The protocol enables heterogeneous systems that include clocks of various inherent precision, resolution, and stability to synchronize to a grandmaster clock. The protocol supports synchronization in the sub-microsecond range with minimal network bandwidth and local clock computing resources. The protocol enhances support for synchronization to better than 1 nanosecond. The protocol specifies how corrections for path asymmetry are made, if the asymmetry values are known. The grandmaster can be synchronized to a source of time external to the system, if time traceable to international standards or other source of time is required. The protocol provides information for devices to compute Coordinated Universal Time (UTC) from the protocol distributed time, if the grandmaster is traceable to international standards and is able to access pending leap second changes. Options are also provided to allow end devices to compute other time scales from the protocol distributed time scale.
 
The protocol defines timing domains in which system timing is consistent. The protocol establishes the timing topology. The default behavior of the protocol allows simple systems to be installed and operated without requiring the administrative attention of users to determine the system timing topology.
 
The standard defines all needed data types, message formats, required computations, internal states, the behavior of devices with respect to transmitting, receiving, and processing protocol communications. The standard provides for the management of protocol artifacts in devices. The standard defines formal mechanisms for message extensions and the requirements for profiles that allow customization for specific application domains.
 
The standard defines conformance requirements. Optional specifications are provided for protocol security. This standard documents conditions under which this standard is backward compatible with IEEE 1588-2008."
P1721 IM/MBM - TC25 Standard for Objective Measurement of Systemic Arterial Blood Pressure in Humans The document covers two topics concerning systemic arterial blood pressure in humans. The first topic is objective measurement and analysis of systemic arterial pulses. The second topic is objective measurement of systemic arterial blood pressure. Adaptations, extensions, and connections to existing standards (IEEE 181-2003, IEEE 1073-2000) are considered enabling seamless integration of blood pressure measurement (BPM) with clinical data recording (electronic health monitoring). The standard considers only objective techniques for BPM assuring that the measurement process satisfies the current standards for evaluating and expressing the uncertainty of the measurement results along with traceability, down to the device that was actually used to transduce the signal.
