Histogram Plot
The histogram plot contains a histogram of the results obtained
during the most recent capture burst (see Figure 24). This
shows the number of occurrences for each code in the results.
See the Generating a Histogram of the ADC Code Distribution
section for more information.
Histogram Analysis
The
Histogram Analysis
pane displays important analysis
parameters on the data in the histogram plot. The indicators are
displayed in volts (
V
) and codes (
LSB
), unless otherwise specified.
The analysis items reference the signal at the AMP_OUT pin of
the
ADAQ7980
.
The parameters include the following:
•
Max Amplitude
displays the maximum value in the data.
•
Min Amplitude
displays the minimum value in the data.
•
DC Offset/Mean
displays the average value of the data.
•
Transition Noise (Pk-Pk)
displays the peak-to-peak value
of the noise of the signal (displayed in
μV
and
LSB RMS
).
•
Pk-pk Amplitude
displays the difference between the
maximum and minimum values in the data.
•
RMS Noise
displays the rms value of the data (displayed
in
μV
).
•
LSB
displays the equivalent voltage difference between
each code value (displayed in
μV
). This value is determined
by the
Reference Voltage (V)
control in the
Configure
tab.
•
Histogram Width
displays the maximum code in the
histogram minus the minimum code in the histogram
(displayed in
LSB
).
