7.3 Time-Domain Display

The time-domain display tool allows visualization of the ADC response to a given input signal. This tool is useful
for studying the behavior of and debugging any gross problems with the ADC or drive circuits. Trigger a data
capture of the selected number of samples from the ADS1258EVM by using the Capture button in
The captured data are subject to the current interface mode settings. The time-domain plot has Samples on the
x-axis and by default shows the corresponding Codes on the y-axis relative to the specified reference voltage.
The y-axis units can also be changed to Voltage/Temp/Gain using the Unit control in the bottom right. The Temp
and Gain units are only used with the Temp and Gain channel selections, respectively.
The Measurements control on the bottom of
standard deviation. Switching pages to any of the Analysis tools described in the subsequent sections causes
calculations to be performed on the same set of data.
