6.1 Connecting the Hardware

Connect the EVM as shown in Figure 6-1 after installing the software:

  1. Physically connect P2 of the PHI to J2 of the ADS8860EVM. Install the screws to assure a robust connection.
  2. Connect the USB on the PHI to the computer first.
    • LED D5 on the PHI lights up, indicating that the PHI is powered up
    • LEDs D1 and D2 on the PHI start blinking to indicate that the PHI is booted up and communicating with the PC; Figure 6-1 shows the resulting LED indicators
  3. Start the software GUI as shown in Figure 6-2. Notice that the LEDs blink slowly while the FPGA firmware is loaded on the PHI. This process takes a few seconds, then the AVDD and DVDD power supplies turn on.
  4. Connect the signal generator. The input range is 0 V to 5 V. A common input signal applied is a 4.9-VPP signal with a 2.5-V offset. This signal is adjusted just below the full-scale range to avoid clipping.
