Software
HISTOGRAM TAB
The
Histogram
tab generates a histogram using the gathered
samples and processes the data, calculating the peak-to-peak
noise, rms noise, and resolution (see Figure 19). There is only
one histogram tab for current and voltage inputs.
Histogram Graph and Controls
The data histogram graph (Label 26 in Figure 19) shows the
number of times each sample of the ADC output occurs. Zoom
in on the data using the control toolbar (Label 27 in Figure 19)
in the graph. Change the scales on the graph by typing values
into the x-axis and y-axis.
Analysis Input
The data used to generate the histogram graph (Label 26 in
Figure 19) and the
Noise Analysis
section (Label 28 in Figure 19)
is set by the
Noise Analysis
box (Label 29 in Figure 19). All the
enabled inputs appear here in the
Noise Analysis
box.
Noise Analysis
The
Noise Analysis
section (Label 28 in Figure 19) displays the
results of the noise analysis for the selected analysis input,
including both noise and resolution measurements.
Display Units and Axis Controls
Click the
Units
dropdown box (Label 30 in Figure 19) to select
whether the data graph displays in units of voltages/amps or
codes. This control is independent for each graph. The axis
controls switch between autoscale and fixed. When autoscale is
selected, the axis automatically adjusts to show the entire range
of the ADC results after each batch of samples. When fixed is
selected, the axis range can be set by the user. However, these
ranges do not automatically adjust after each batch of samples.
Device Error
The
Device Error
indicator (Label 31 in Figure 19) illuminates
in the
Histogram
tab when a CRC error or an error in the ADC
is detected. More specific information of the error can be
obtained by clicking
Summary
in the
Configuration
tab
(Label 12 in Figure 16).
