POWERING UP THE BOARD
The evaluation board, as configured from the factory, uses the
local LDOs for power where necessary. A ±15 V dc lab supply
must be connected to the board. Test points (yellow and white)
are provided for these external supplies.

RUNNING THE SOFTWARE WITH THE HARDWARE
CONNECTED
The evaluation board includes software for analyzing the
ADAS3022
. The

is required when using the
software. The software is used to perform the following tests:
•
Histogram tests for determining code transition noise (dc)
•
Time domain analysis
•
Fast Fourier transforms (FFT) for signal-to-noise ratio
(SNR), SNR and distortion (SINAD), total harmonic
distortion (THD), and spurious free dynamic range (SFDR)
