  1. Existing Industrial Solutions and Virtual Instrumentation Integration into GANMVL Reinhard Bacher, Michael Seebach DESY

  2. Motivation • Use of stand-alone, off-the shelf T&M (test and measurement) instruments such as • Oscilloscopes • Spectrum analyzers • Signal and function generators • Digital multi-meters etc. • Scenarios: • In a mobile environment • For a short time • On short notice etc. R. Bacher et al. VI Integration

  3. Objectives • 1st Priority: Visualization and / or control of T&M-specific functions through the MVL framework from a remote site • 2nd Priority: Integration of the T&M specific data-flow into the MVL framework R. Bacher et al. VI Integration

  4. Off-the Shelf T&M Instruments • Databus interface: • USB • TCP/IP Ethernet • GPIB • Operating system: • Proprietary operating system • Windows (desktop-type, embedded / restricted) R. Bacher et al. VI Integration

  5. Scenario 1 Analog / Digital I/O T&M Instrument (e.g. Oscilloscope) Vendor-Specific Application Software VNC Server / Remote Desktop Server Intranet / Internet VNC Client / Remote Desktop Client for Instrument Control and Data Visualization R. Bacher et al. VI Integration

  6. Scenario 2 Analog / Digital I/O T&M Instrument (e.g. Oscilloscope) Vendor-Specific Application Software Web Server Intranet / Internet Web Browser Customized Page (e.g. HTML, Applet) for Instrument Control and Data Visualization R. Bacher et al. VI Integration

  7. Scenario 3 Analog / Digital I/O T&M Instrument (e.g. Oscilloscope) Vendor-Specific Server Software Intranet / Internet Vendor-Specific Client Software (Licenses!) Vendor-Specific Application Software (Licenses!) for Instrument Control and Data Visualization / Data Integration R. Bacher et al. VI Integration

  8. Scenario 4 Analog / Digital I/O T&M Instrument (e.g. Oscilloscope) Data Bus Interface (e.g. GPIB, RS232, PXI, TCP/IP) Data Bus Link Bus-Specific Data Bus Driver Software Vendor-Specific Instrument Driver Software Customized Application (e.g. LabView) for Instrument Control and Data Visualization / Data Integration Web Server Intranet / Internet Web Browser Customized Page (e.g. HTML, Applet) for Instrument Control and Data Visualization R. Bacher et al. VI Integration

  9. MVL Instrument Integration Client Web Server-based Integration VNC Remote Desktop Server-based Integration IVI-based Integration Vendor-specific Application Software T&M Instrument R. Bacher et al. VI Integration

  10. Standardization by Industry • Problem: • Vendor-specific instrument drivers • Vendor-specific virtual instrument software • Proposed MVL solution: • Generic virtual instruments based on • VISA-compliant databus drivers (VISA = Virtual Instrument Software Architecture) • IVI-compliant instrument drivers (IVI = Interchangeable Virtual Instrument) • LabView / Web-Publishing R. Bacher et al. VI Integration

  11. IVI Foundation Members e.g. • Agilent Technologies • Keithley Instruments • National Instruments • Rohde & Schwarz • Tektronix • LeCroy R. Bacher et al. VI Integration

  12. IVI-Supported Instrument Classes • DC power supply • Digital multi-meter • Function & Arbitrary generator • Oscilloscope • Power meter • RF signal generator • Spectrum analyzer • Switch R. Bacher et al. VI Integration

  13. IVI: Example IviScopeBase Attributes Acquisition Start Time Acquisition Type Channel Count Channel Enabled Channel Item (IVI-COM only) Channel Name (IVI-COM only) Horizontal Minimum Number of Points Horizontal Record Length Horizontal Sample Rate Horizontal Time Per Record Input Impedance Maximum Input Frequency IviScopeBase Functions Abort Acquisition Status Actual Record Length (IVI-C only) Configure Acquisition Record Configure Acquisition Type (IVI-C only) Configure Channel Configure Channel Characteristics Configure Edge Trigger Source Configure Trigger Configure Trigger Coupling (IVI-C only) GetChannelName (IVI-C Only) Fetch Waveform Initiate Acquisition Is Invalid Waveform Element Read Waveform Sample Rate (IVI-C only) R. Bacher et al. VI Integration

  14. IVI Architecture COM specific e.g. ividmm.dll IVIConfigurationStore.xml e.g. ke2700_32.dll e.g. VISA Library Specific Instruments R. Bacher et al. VI Integration

  15. Prerequisites • Install “IVI Shared Components” and “IVI –supported Instruments” class libraries (→ IVI foundation) • Install “NI IVI Compliance Package” (→ National Instruments) • Install “VISA Runtime” and “NI Measurement and Automation Explorer (MAX)” (→ National Instruments) R. Bacher et al. VI Integration

  16. Instrument Integration (1/6) • Connect instrument to data bus and configure communication parameters, e.g. IP address • Install IVI class compliant specific driver (→ instrument vendor or National Instruments) R. Bacher et al. VI Integration

  17. Instrument Integration (2/6) • Configure the device interface parameters using MAX • e.g. Specify / check IP address and TCP-port number R. Bacher et al. VI Integration

  18. Instrument Integration (3/6) • Configure IVI Driver: • Specify / check hardware asset R. Bacher et al. VI Integration

  19. Instrument Integration (4/6) • Configure IVI Driver: • Specify / check instrument driver software module R. Bacher et al. VI Integration

  20. Instrument Integration (5/6) • Configure IVI Driver: • Create driver session • Hardware • Software R. Bacher et al. VI Integration

  21. Instrument Integration (6/6) • Configure IVI Driver: • Create logical name • Save IVI configuration R. Bacher et al. VI Integration

  22. Generic Instrument Test Applications R. Bacher et al. VI Integration
