  1. With the EVM GUI open on the PC, navigate to the Control tab.
  2. To calibrate the ADC, click Cal Triggered/Running once, then click it again. This will stop and restart the Calibration engine.
    Note: This calibrate button executes a calibration sequence that is required for full performance. This calibration is performed automatically during the Section 3.9 step but must be performed again, any time the sampling rate changes, after significant temperature change of the ADC, or after exiting the power-down mode. See ADC12DJ5200RF 10.4-GSPS Single Channel or 5.2-GSPS Dual Channel, 12-bit, RF for details regarding the necessary calibration sequence.

  3. To enable background calibration, use the following steps:
    • Navigate to the JESD204C tab and click on JESD Block Enable to stop the JESD204C block.
    • Navigate back to the Control tab and click on Enable Calibration Block to disable calibration and allow setting changes.
    • Click on Enable Background Cal.
    • If background offset calibration is desired also, click on Enable Background Offset Cal.
    • Click on Enable Calibration Block to enable the calibration subsystem again.
    • Navigate to the JESD204C tab and click on JESD Block Enable to re-start the JESD204C block.
    • Navigate back to the Control tab and click the Cal Triggered/Running button once, then click it again. This restarts the Calibration engine.
  4. To disable background calibration, use the following steps:
    • Navigate to the JESD204C tab and click on JESD Block Enable to stop the JESD204C block.
    • Navigate back to the Control tab and click on Enable Calibration Block to disable calibration and allow setting changes.
    • If background offset calibration was enabled, click on Enable Background Offset Cal to disable the feature.
    • Click on Enable Background Cal to disable the feature.
    • Click on Enable Calibration Block to enable the calibration subsystem again.
    • Navigate to the JESD204C tab and click on JESD Block Enable to restart the JESD204C block.
    • Navigate back to the Control tab and click the Cal Triggered/Running button once, then click it again. This restarts the Calibration engine.
