Use the Instrument Controller (ICsc) to self-calibrate the VSTs in your system.

Note The ICsc window should be open on the host computer from a shortcut place at: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup when ICsc is installed.
  1. Click Launch VST Self-Calibration in the NI ICsc window.
    Note NI recommends that no external signals are transmitted to the RF input port during self-calibration.

    The ICsc Self-Calibration window opens.

  2. Select the self-calibration mode for your system configuration.
    • Select Multi VST for common LO configurations.
    • Select Independent VST for independent LO configurations.
  3. Populate the instruments array control with the VSTs in your system.
    Note For common LO configurations, you must populate the VSTs in the order of the daisy-chain reference clock.

  4. Click START.
    Clicking START disables the controls. The self-calibration status updates from Ready, to Active, to Calibration Complete. An error message displays if an error occurs.
    Note Self-calibration duration depends on configuration.
    • Multi VST—Duration is approximately 30 minutes per VST. Self-calibration occurs sequentially following the order of the INSTRUMENTS array control.
    • Independent VST—Duration is approximately 30 minutes. All VST self-calibration occurs in parallel.
  5. Close the ICsc Self-Calibration window.
Note Independent LO configurations can also perform self-calibration in InstrumentStudio. Refer to Self-Calibrating the PXIe-5842 with InstrumentStudio in PXIe-5842 User Manual for more information. Self-calibrating the VSTs in InstrumentStudio is approximately 30 minutes per VST.
