HISTOGRAM TAB

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).
