TAKING SAMPLES
To initiate a conversion and capture the sample data, click the
Sample button or the Continuous button. Both the Sample
and the Continuous buttons are located on the top right hand
corner of the Data Capture tab. When you click the Sample
button, the software instructs the EVAL-CED1Z board to take
the required number of samples at the required frequency from
the evaluation board. The EVAL-AD7262/ AD7264 runs with
sampling speeds less than or equal to 1 MSPS. You can choose
the sampling frequency up to this rate and the number of
samples to be taken.
The samples taken are then uploaded and displayed. An FFT
and/or histogram can be calculated and displayed. If you click
the Continuous button, the software repeats the process indefi-
nitely until you click Stop. (The Continuous button switches
to Stop when clicked). You can switch between displaying data
from ADC A, ADC B, or both while the software is running
continuously.
Note that no data appears on the screen if the ADCs are not
powered on. The ADC A, B, button in the Part Information
section should be set to ON to power on both ADCs.
