The
ADC Capture and Analysis
tab consists of various analysis routines and displays. This tab is used to:
•
Set the capture mode to finite or continuous
•
Set the number of samples (block size) in Finite Capture mode
•
Set the display to volts or codes
•
Set the filter type to None or Notch
•
Set the Notch Freq to 50 or 60 Hz when the filter type is set to Notch
•
Set Analysis Type to All Domain or Time Domain only
•
Auto save after capture selector
•
Acquire the data by clicking the

notification is given after every capture.
The captured data can be analyzed in time domain and frequency domain; the data can also be displayed
in a histogram format. The ADC Capture and Analysis tab is shown in
Figure 28
.
By selecting the Time Domain plot, the data are displayed in time domain format. The units can be
converted from codes to volts using the drop-down window in the top-left corner of the GUI. For the time
domain plot, the mean voltage, root mean square (RMS) voltage, and peak-to-peak voltage are displayed
in the
Test Results
section, which is a pop-up window that opens when the
Scope Analysis
button is
clicked. The Scope Analysis: Test Results section pop-up window is shown in
Figure 29
