Add module to existing system

Follow the steps below to insert more modules into an existing diagnostics system.

  1. Configure digitizer

    Decide what kind of modules and how many modules to use (decide channel number, sampling speed, digitizer category, etc…), and apply for the joint purchase of modules.
    *If the modules you wish to use are not available at LABCOM, let us know via this online form.
    *If you're going to use PXI-6115, PXI-6133 or PXI-6143, make sure to buy Terminal Block (a connection converter for PXI Modules) as well.

  2. Apply for installation

    Name the modules and give them station/device numbers. Make application for the installation/augmentation of a diagnostics system.

  3. Prepare for data transmission

    Follow the steps below. (Refer to the installation page for details.)
    1. Check the layout of coaxical cable ducts and optical terminal boxes and decide a path for data transmission. If you wish to use BNC connectors, make request for the allotment of coaxing cable duct for BNC use. Make everything ready for transmission (insert modules, connect cables and so on).
    2. Have the existing diagnostics timing system wired to the newly-added modules.
    3. Let us know when all the things are ready. Call 2452 or send email to .
      *LABCOM conducts an operation test and let you know when we confirm that they're working properly.

  4. Set digitizer and timing

    Go to Setting for data acquisition to set digitizer's parameters of the added modules. Click here to see how to do the setting.
    If you wish to use another trigger/clock channel of the demodulator, you set parameters via a software application “Plasma Diagnostics Control Client System”. Click here to see how to do the setting.

Module addition should be now completed.
