X-scale
This button allows the user to have a fixed x-axis or a dynamic
x-axis. When the x-axis is fixed, the number of samples to
display is entered in the X-scale Samples text box.
Analysis
After Sampling
The software can process the conversions as they are gathered,
or it can process the samples when the ADC has completed the
selected number of conversions.
Analyse All Samples
This feature allows you to fix the sample size used for analyzing.
Alternatively, the software can process all samples gathered.
When the Analyse Last # Samples option is selected, the
sample size must be entered in the Last # Samples text box.
The software captures all samples generated by the AD7194. If
the software fails to gather all samples, then the message shown
in Figure 6 appears. The software may drop samples for the
following reasons:
• The data is being analyzed in parallel with the gathering of
samples. You should delay the analysis until the samples
are gathered.
• Other programs are running on the PC.
• PC is too slow.
