OVERVIEW OF THE MAIN WINDOW
The main window of the software is shown in Figure 15 and has
the features described in this section.
File Menu (Section 1)
The File menu (labeled 1 in Figure 15) offers the choice to
•
Load data: load previously captured data or example files in
.tsv (tab separated values) format for analysis (see Figure 16).
(The default location for example files is C:\Program
Files\Analog Devices\EVAL-AD7276_77_78SDZ.)
•
Save Data as .tsv: save captured data in .tsv format for
future analysis (see Figure 17).
•
Print Front Panel Picture: print the main window to the
default printer.
•
Save Picture: save the current screen capture.
•
Exit: quit the application.

Part Information Box (Section 2)
The Part Information box (labeled 2 in Figure 15) displays the
generic being evaluated and is for informational purposes only.
Resolution Box (Section 3)
The Resolution box (labeled 3 in Figure 15) displays the
resolution of the
AD7276
in bits.
Sampling Rate Box (Section 4)
The default sampling frequency in the Sampling Rate box
(labeled 4 in Figure 15) matches the maximum sample rate of
the ADC being evaluated. Although you can adjust the sampling
frequency, there are limitations in terms of the sample frequencies
that can be entered. If an unusable sample frequency is input, the
software automatically adjusts the sample frequency accordingly.
Units can be entered as, for example, 10k for 10,000 Hz. The
software automatically adjusts the sample frequency according
to the ability of the ADC being evaluated. For example, if you
enter a value that is beyond the ability of the device, the software
indicates this and reverts to the maximum sample frequency.
Exit Button (Section 5)
Clicking Exit (labeled 5 in Figure 15) closes the software.
Alternatively, you can select Exit from the File menu.
Busy LED (Section 6)
The Busy LED (labeled 6 in Figure 15) indicates when a read
from the
EVAL-SDP-CB1Z
board is in progress.
Tabs Area (Section 7)
There are four tabs available in the tabs area (labeled 7 in Figure 15)
of the main window: Waveform, Histogram, FFT, and Summary.
These tabs display the data in different formats. Navigation tools
are provided within each tab to allow you to control the cursor,
zooming, and panning (see Figure 15) within the graphs displayed.
Each tab is described in more detail in the Generating a
Waveform Analysis Report; Generating a Histogram of the
ADC Code Distribution; Generating a Fast Fourier Transform
of AC Characteristics; and Generating a Summary of the
Waveform, Histogram, and Fast Fourier Transform sections.
# Samples Box (Section 8)
The # Samples box (labeled 8 in Figure 15) allows you to select
the number of samples to analyze. When Sample or Continuous
is clicked, the software requests this number of samples to be taken.
This is the total number of samples taken on all channels.
Sample Button (Section 9)
Clicking Sample (labeled 9 in Figure 15) performs a single
capture, acquiring a set number of samples at the selected
sampling rate.
Continuous Button (Section 10)
Clicking Continuous (labeled 10 in Figure 15) performs a
continuous capture from the ADC. Clicking Continuous a
second time stops sampling.
