Figure 5-14. Data Capture Window
Conversion data collects when the
Collect Data
button is pressed. The button will change to
Stop Collect
and by
pressing the button while in this state the collection of conversion data will stop, otherwise the data is collected
for the number of
Samples
as given. The number of
Samples
can be changed prior to pressing
Collect Data
by
selecting the
Samples
and directly entering the desired number of samples or by clicking on the up and down
arrows. The number of samples cannot be changed while the data is being collected.
When the
Collect Data
operation is complete, the data will display with the calculated channel statistics and a
plot of the data in the chart window. Various icons for viewing the data include zoom, pan, and home. The home
icon restores the graph to show all data collected. The viewing icons are underneath the statistics information on
the right side of the GUI.
Also on the right side of the chart window is a slide-out menu where configuration settings are displayed and
changes can be made for data collection.
5.2.2.1 Channel Statistics
When data collection completes, statistical information displays along with the charted data. The statistical
display for
Time Domain
and
Histogram
are the same, but the
FFT
statistics differ. As the TLA2024 is primarily a
DC measurement device, the FFT plot and information may have little meaning.
5.2.2.1.1 Time Domain and Histogram Statistics
The
Time Domain
and
Histogram
plots share the same statistical information:
• Input
Channels
selected
•
Min
code within the data set
•
Max
code within the data set
•
Mean
code value within the data set
•
Std Dev
representing the standard deviation within the data set
•
Pk-to-Pk
representing the total noise peak-to-peak within the data set
•
Eff. Res
representing the effective resolution as number of bits with the value in parenthesis showing the
noise-free number of bits
