Physically connect P2 of the PHI to J10 of the ADS8555EVM. Install the screws to assure a robust connection.
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.
As shown in Figure 6-2, start the software GUI. Notice that the LEDs blink slowly when the FPGA firmware
is loaded on the PHI. This process takes a few seconds, afterwards the AVDD and DVDD
power supplies turn on.
Connect the external ±15-V power supplies and GND
to J1. This connection generates the AVDD, HVDD, and HVSS supplies (HVDD = 12 V,
HVSS = –12 V, and AVDD = 5 V).
Connect the signal generator. The default input
range is ±10 V (or 10 Vpk). A common input signal applied is a sinusoidal 1-kHz,
9.9-Vpk signal with a 0-V offset. This signal is adjusted just below the full-scale
range to avoid clipping.
