1 Quick Start Guide One Technology Way P.O. Box 9106 Norwood, MA , U.S.A. Tel: Fax: Quick Start Guide for using the Triggered Capture Feature of the HSC-ADC-EVALCZ Capture Board with the AD9629 ADC Evaluation Board TYPICAL SETUP Figure 1. AD9629 Evaluation Board and HSC-ADC-EVALCZ Data Capture Board EQUIPMENT NEEDED 2 switching power supplies (6.0 V, 2.5 A), CUI EPS060250UH-PHP-SZ (or equivalent) Analog signal source and anti aliasing filter (if test signal is to be applied) Analog Clock source (if not using the on-board crystal) PC running Windows USB 2.0 port recommended AD9629 Evaluation Board (AD9629-xxEBZ) HSC-ADC-EVALCZ FPGA Data Capture Board HELPFUL DOCUMENTS AD9649_29_09 User Guide - VisualAnalog Converter Evaluation Tool User Manual, AN-905 Rev. PrA Page 1 of 6

2 AD9629 Quickstart Guide High Speed ADC SPI Control Software User Manual, AN-878 Interfacing to High Speed ADCs via SPI, AN-877 SOFTWARE NEEDED VisualAnalog ( ) SPIController ( ) ad9649_fifo5.bin FPGA file (supplied separately) Documents are available at For any questions, please send an to highspeed.converters@analog.com. TESTING (Note: Though AD9629 is mentioned in this document, this procedure also applies to the AD9649 and AD9609) 1. Setup the AD9629 evaluation kit as described in the AD9629 User Guide ( ). Verify that the evaluation kit is converting and processing data as specified in the User Guide. a. Make sure that the HSC-ADC-EVALCZ jumper J9 is in the 2.5V position. 2. Additionally, hardware connections to the SMA connectors SMA1 J7 and SMA2 J5 (see Figure 1) are needed. The voltage on SMA2 will be monitored. A 0V 2.5V rising edge will later be applied to SMA1 to trigger capture. Setup appropriate hardware to accomplish this. 3. In VisualAnalog, navigate to the Samples Canvas: File New... Select the Samples Canvas. Click Open. 4. You might get a window that looks like this: If so, click Yes and proceed. Rev. PrA Page 2 of 6

Clicking the Settings button above will bring up a window with three tabs. In the Capture Board tab, enter a number like into the Fill Delay (ms) field. The purpose for this number will be seen later. Then browse to the location of the ad9649_fifo5.bin file (supplied separately), select it and click Open in the browse window, and the click Program as shown below. After the Program button is clicked, the voltage on SMA2 should move from a few millivolts up to about 2.5V. Click on the OK button in the ADC Data Capture Settings window (shown below). 7. Start SPIController software, if it is not already running. Use the menu bar to navigate File Cfg Open. In the default directory that comes up, there should be a file with a name similar to AD9629_12Bit_80MSspiR03.cfg. Select this file and click Open. This takes you to the AD9629 configuration environment. 8. In SPIController, again navigate File Cfg Open. This time choose the file named ADFPGAspiR03.cfg. Click Open. This will produce a register read/write window. Enter values as shown below. This FPGA register write enables triggered capture. Rev. PrA Page 3 of 6

4 AD9629 Quickstart Guide After writing Register 0x06 = 0x02, click on Read to be sure that 2 appears in the Read field. 9. Now the evaluation setup is configured for externally triggered capture. Push the Run button on the VisualAnalog top bar. The evaluation board will now wait for a rising 2.5V edge to be applied to SMA1. Voltage on SMA2 should still be 2.5V, as mentioned in Step 6. This indicates that the system is ready to capture data, triggered by an edge to be applied to SMA Apply a rising edge (2.5V) on SMA1. This edge needs to be applied before the end of the Fill Delay interval specified in Step 6. If was entered in Step 6, you will have milliseconds from when the Run button was pushed, to apply the edge. 11. After the Fill Delay interval has passed, data that was captured by external trigger will appear graphically on the VisualAnalog canvas. Note that the data will not appear when the trigger edge is applied. It will appear after the Fill Delay interval has passed. 12. To store the captured data, push the Settings button on the graph window. Rev. PrA Page 4 of 6

In the Data Settings tab, check the boxes indicated below. Push the Browse... button to navigate to the location where data is to be stored, and enter desired filename. Rev. PrA Page 5 of 6

6 AD9629 Quickstart Guide 15. Optional Step: In the Graph Window tab, the Float automatically check box, if checked, causes the graph to pop-up and float when the Run button is pushed. To disable this, uncheck this box. Push OK to save the settings and close the window. 16. The data captured by external trigger will be saved to the file specified in Step 14. Rev. PrA Page 6 of 6
