Phase Compensation - Texas Instruments ADS86 EVM-PDK Series User Manual

www.ti.com
When the ALARM feature is enabled, the capture data window shows the indicators for high and low
thresholds based on the values programmed. After data capture, if the device detects an ALARM event,
EVM diode D1 turns on with a red indicator light. The GUI monitors the status of the ALARM pin on the
device. When an ALARM is detected, the ALARM indicator on the GUI starts flashing.
The user can read the status of tripped alarms by clicking the Diagnose Alarm? button. The user can
also read the ALARM register contents from register map view to detect the state of tripped and active
alarms.

Phase Compensation

The ADS86xxEVM GUI includes an analysis page for compensating the phase of signals captured in auto
mode. When the signals on different channels are sampled in auto mode, a deterministic phase difference
between signals is introduced resulting from the time difference between sampling instants. The phase
difference is dependent on sampling rate, input signal frequency, number of channels, and initial phase
difference. The phase compensation analysis page compensates for the introduced phase difference and
provides the results after phase compensation. For details on phase compensation, see the reference
guide Phase Compensated 8-CH Multiplexed Data Acquisition System for Power Automation
The phase compensation analysis page can be activated from the Smart App menu.
