Setup Procedure
•
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 re-enable the calibration subsystem
•
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 re-enable the calibration subsystem.
•
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.
3.11 Open the HSDC Software and Load the FPGA Image to the TSW14J57EVM
1. Open the HSDC Pro software.
2. Click OK to confirm the serial number of the TSW14J57EVM device. If multiple TSWxxxxx boards are
connected, select the model and serial number for the one connected to the ADC12DJ5200RFEVM.
3. Select the ADC12DJxx00RF_JMODE1 device from the ADC select drop-down in the top left corner.
4. When prompted, click Yes to update the firmware.
If the user configures the EVM with options other than the default register values, different
instructions may be required for selecting the device in HSDC Pro. See
5. Enter the ADC Output Data Rate (ƒ
must be equal to the actual sampling rate of the device and must be updated if the sampling rate changes.
3.12 Capture Data Using the HSDC Pro Software
The following steps show how to capture data using the HSDC Pro software (see
1. Select the test to perform.
2. Select the data view.
3. Select the channel to view.
4. Click the capture button to capture new data.
Additional tips:
•
Use the Notch Frequency Bins from the Test Options file menu to remove bins around DC (eliminate DC
noise and offset) or the fundamental (eliminate phase noise from signal generators).
•
Open the Capture Option dialog from the Data Capture Options file menu to change the capture depth or to
enable Continuous Capture or FFT averaging.
•
For analyzing only a portion of the spectrum, use the Single Tone test with the Bandwidth Integration Markers
from the Test Options file menu. The Channel Power test is also useful.
•
For analyzing only a subset of the captured data, set the Analysis Window (samples) setting to a value less
than the number of total samples captured and move the green or red markers in the small transient data
window at the top of the screen to select the data subset of interest.
