The data is acquired from the EVM by clicking ACQUIRE button. The number of samples (block size) to
be acquired must be given in the space provided. The CONTINUOUS button acquires the data from the
EVM continuously in the designated block size.
Scope Sub-Tab
The Scope sub-tab displays the data in the time-domain. The units are converted from codes to volts
using the voltage reference value set in the ADC Registers tab and are plotted as either input referred
(output divided by PGA gain setting) or non-input referred using the checkbox located in the top right
corner of the GUI. The Scope Analysis button activates a pop-up that displays the mean voltage, root
mean square (RMS) voltage and peak to peak voltage for noise analysis.
