Commtest Instruments Driver

admin

An instrument driver, in the context of test and measurement (T&M) application development, is a set of software routines that simplifies remote instrument control. Instrument drivers are specified by the IVI Foundation[1] and define an I/O abstraction layer using the virtual instrument software architecture (VISA). The VISA hardware abstraction layer provides an interface-independent communication channel to T&M instruments. Furthermore, the instrument drivers encapsulate the Standard Commands for Programmable Instruments (SCPI) commands, which are an ASCII-based set of commands for reading and writing instrument settings and measurement data. This standard allows an abstract way of using various programming languages to program remote-control applications instead of using SCPI commands. An instrument driver usually has a well-defined API.

Standards[edit]

Install the contrib drivers with pip. Pip install qcodescontribdrivers Contributing. This repository is open for contribution of new drivers, as well as improvements to existing drivers. Each driver should contain an implementation of the driver and a Jupyter notebook showing how the driver should be used. GE Measurement & Control, Christchurch (formerly Commtest Instruments) is a global leader in the development and production of vibration analysis and monitoring instruments. Vibration analysis detects early precursors to failure, allowing machinery repair or replacement before expensive failures occur.

VXIplug&play instrument driver[edit]

The VXIplug&play Systems Alliance was founded in 1993[2] with the aim of unifying VXI hardware and software to achieve 'plug and play' interoperability for VXI and GPIB instruments. As part of the unifying process, VXIplug&play instrument drivers[3] were also defined.

IVI instrument drivers[edit]

When the IVI Foundation took over the Alliance in 2002, it defined a new generation of instrument drivers to replace the VXIplug&play standard. The IVI instrument driver specification intends to overcome the drawbacks of VXIplug&play. These IVI (Interchangeable Virtual Instrumentation) drivers[4] are currently defined in three different architectures:

  1. The IVI-COM driver architecture[5] is based on the Microsoft Component Object Model.
  2. The IVI-C drivers are based on C programming language shared components (shared libraries).
  3. The IVI.NET driver architecture was specified in 2010.[5][6] The IVI.NET drivers are based on the .NET framework.

Remote control of instrumentation[edit]

Driver

Instrument drivers allow quicker development of remote-control applications for instrumentation. The drivers reduce the difficulty of string formatting when using SCPI commands by providing a well-defined API. The IVI and VXIplug&play Instrument Drivers use the VISA as the hardware abstraction layer so that hardware-independent applications can be developed.

I/O hardware abstraction layer VISA[edit]

The VISA library allows test and measurement equipment to be connected through various hardware interfaces. The following interfaces are available:

  • GPIB/IEEE-488
  • VXI-11[7] (over TCP/IP)
  • USB488/USBTMC (USB Test & Measurement), USB Test & Measurement Class Specification[8]
  • HiSLIP[9] (over TCP/IP).

LXI[edit]

The LAN eXtensions for Instrumentation (LXI) standard defines the communications protocols for controlling test and measurement systems using Ethernet. The standard requires vendors to offer IVI compliant instrument drivers.

We understand that what you value most is the ability to complete your work as quickly and comfortably as possible, confident that you are getting high quality data first time, every time. With customer feedback directly guiding our product development, the all-new vb7 instrument offers usability enhancements that are sure to make your working relationship a pleasant one” says Jack Dischner, President.Commtest’s foray into the U.S. market represents a significant challenge to its competition. The company’s vibration analysis products are cost-competitive and Commtest is able to respond quickly to adapt their product offerings to meet customers’ needs. They also offer the only five-year warranty in the industry – a benefit that customers rarely have to pay for. According to Jack, ‘our warranty claims are the lowest in the industry.’ The vb7 instrument is an all-in-one tool suitable for every level of vibration analyst, from novice through to expert. The Ascent software contains the collective experience of over 25 years of expert in-depth machine fault analysis.About Commtest

    Commtest Instruments Ltd

    Founded in 1989 in New Zealand, Commtest Instruments Ltd (Commtest) is a privately held company whose mission is to bring the benefits of vibration analysis to mainstream industry. Small and medium sized companies were previously not able to implement condition monitoring programs due to the high cost of data collection and analyzing equipment. With Commtest’s product line, companies of all sizes can now afford a condition monitoring program and realize the return on investment from equipment optimization.
