INSTALLING THE SOFTWARE To install the software, go to www.analog.com/fifo, and download and install the following: • • Open the VisualAnalog software on the PC. The AD9250 or the AD6673 should be listed in the status bar of the New Canvas window (see Figure 2). VisualAnalog, Rev 1.9.20.21 or later. SPI Control Software, Rev 1.0.91.3 or later. 1. 2. 3. 4. 5. 6. 7. Connect the AD9250 or the AD6673 evaluation board and the HSC-ADC-EVALDZ board together, as shown in Figure 1. Connect one 6 V, 2 A switching power supply (such as the CUI EPS060250UH-PHP-SZ supplied) to the AD9250 or the AD6673 board. Ensure that the 6 V power supply is used. Connect one 12 V, 3.3 A switching power supply (such as the V-Infinity ETSA120330UDC-P5P-SZ supplied) to the HSC-ADC-EVALDZ board. Ensure that a 12 V power supply is used. Connect the HSC-ADC-EVALDZ board to the PC with a USB cable. (Connect to P702.) On the AD9250 or the AD6673 evaluation board, ensure that the jumpers are installed on the P205, P206, and P204 headers for default setup. On the AD9250 or the AD6673 evaluation board, provide a clean, low jitter clock source to Connector J505 at the desired ADC conversion rate. If the AD9250 or the AD6673 input clock divider is used, provide a clock into the J505 connector at the appropriate rate. The input clock level must be between 10 dBm and 14 dBm. On the AD9250 or the AD6673 evaluation board, use a clean signal generator with low phase noise to provide an input signal to the analog input at Connector J301 (Channel A) and/or Connector J303 (Channel B). Use a 1 m, shielded, RG-58, 50 Ω coaxial cable to connect the signal generator. For best results, use a narrow-band, band-pass filter with 50 Ω terminations and an appropriate center frequency. (Analog Devices uses TTE, Allen Avionics, and K&L bandpass filters.) For the input level to be near the full-scale of the ADC, the generator level must be set to 8 dBm to 12 dBm, and this level depends on the input frequency and any losses in band-pass filters. 11140-002 SETTING UP THE HARDWARE AND THE SOFTWARE Figure 2. New Canvas Window 9. Select the template that corresponds to the type of testing that needs to be performed. 10. Select the ADC Data Capture Settings window and click the Capture Board tab (see the red box in Figure 3). 11. In the FPGA box, select the AD9250_12_04_11_1225.mcs program or the AD6673_12_04_11_1225.mcs program to configure the FPGA. 12. Click Program to download the file to the FPGA. The CONFIG_DONE LED should illuminate on the HSCADC-EVALDZ board indicating that the FPGA has been correctly programmed.

Open the SPIController software. If prompted for a configuration file, select the AD9250_14Bit_250MSspiR03.cfg or AD6673_14Bit_250MSspiR03.cfg. If not, check the title bar of the window to see which configuration is loaded. If necessary, choose Cfg Open from the File menu and select the correct configuration file. Note that the CHIP ID(1) field may be filled whether the correct SPIController configuration file is loaded or not. 14. In the SPIController software, click File > MacroGroup Open (see Figure 4). 15. Select the AD9250_M2L2_SPI.mgp or the AD6673_M2L2_SPI.mgp file and click Open. 16. Select Config > Launch Macro Editor (see Figure 5). The MarcoEditor window opens (see Figure 6).

Before running the macro, unplug the power connector to the AD9250 or the AD6673 evaluation board and reconnect it. 18. Click Run Macro to configure the AD9250 or the AD6673 (see highlighted red in Figure 7). 19. Click Run ( ) in the VisualAnalog software. 20. Adjust the amplitude of the input signal so that the fundamental is at the desired level. (Examine the Fund Power reading in the left panel of the VisualAnalog FFT window.) 21. If desired, click File > Save Form as in the FFT window to save the FFT plot Rev. 0 | Page 6 of 8 Evaluation Board User Guide UG-493 TROUBLESHOOTING FFT Window Remains Blank After Run Is Clicked Four troubleshooting issues include the following: Take the following steps if the FFT window remains blank after Run is clicked: • • • • FFT plot appears abnormal FFT plot appears normal, but the performance is poor FFT window remains blank after clicking Run VisualAnalog indicates FIFO capture timed out • • FFT Plot Appears Abnormal Take the following steps if the FFT plot appears abnormal: • • If a normal noise floor is seen when the signal generator is disconnected from the analog input, ensure that the ADC is not being overdriven. Reduce input level, if necessary. In VisualAnalog, click Settings in the Input Formatter block. Ensure that Number Format is set to the correct encoding (twos complement by default). • • Ensure that the AD9250 or the AD6673 evaluation board is securely connected to the HSC-ADC-EVALDZ board. Disconnect power from both the AD9250 or the AD6673 evaluation board and the HSC-ADC-EVALDZ board, disconnect the USB cable from the HSC-ADC-EVALDZ board, and begin again at Step 1. Ensure that the FPGA has been programmed by verifying that the CONFIG_DONE LED is illuminated on the HSCADC-EVALDZ board. Ensure that the correct FPGA program was installed. VisualAnalog Indicates FIFO Capture Timed Out FFT Plot Appears Normal, but the Performance Is Poor Take the following steps if the VisualAnalog indicates that the FIFO Capture Timed Out: Take the following steps if the FFT plot appears normal but the performance is poor: • • • • • • Ensure that the appropriate filter is being used on the analog input. Ensure that the signal generators for the clock and the analog input are clean (low phase noise). If noncoherent sampling is being used, change the analog input frequency slightly. Ensure that the SPI configuration file matches the product being evaluated. Rev. 0 | Page 7 of 8 Ensure that all power and USB connections are secure. Confirm that the encode clock source is present at Connector J505. UG-493 Evaluation Board User Guide NOTES ESD Caution ESD (electrostatic discharge) sensitive device.
