EVAL-AD7405FMCZ Datasheet, PDF (14/20 Pages) Analog Devices – Full featured evaluation board

UG-690
DESCRIPTION OF MAIN WINDOW
When the software is launched, the main software window
opens (see Figure 14).
The evaluation software panel as shown in Figure 14 has the
following features:
• Menu bar
• Control buttons
• FPGA configuration options
• Data capture display
• AC/DC analysis
Menu Bar
The menu bar, labeled 1 in Figure 14, consists of the File, Edit,
and Help menus.
File Menu
• Save Captured Data. Saves captured data in .csv format for
future analysis.
• Load Captured Data. Loads previously captured data in
comma separated values (.csv) format for analysis.
• Take Screenshot. Saves screenshot of window as a .jpeg file.
• Print Screenshot. Sends screenshot of window to the
default printer.
• Exit. Exits the program.
Edit Menu
• Reinitialize to default. Places the evaluation board in a
known default state.
Help Menu
• Analog Devices Website. Opens the Analog Devices
website in the default browser.
• Context Help. Turns on context sensitive help.
• About. Provides evaluation kit information.

Control Buttons, Drop-Down Boxes, and Indicators
The evaluation software includes the following control buttons,
drop-down boxes, and indicators.
• The Eval Board Connected box (labeled 2 in Figure 14)
indicates whether the EVAL-AD7405FMCZ board has been
detected.
• The FPGA Settings section (labeled 6 in Figure 14) specifies
the MCLK frequency used for the serial interface and the
decimation ratio used by the FPGA to filter the data.
• The Samples drop-down box (labeled 4 in Figure 14)
allows selecting the number of samples to be captured in a
single acquisition.
• Clicking Single Capture (see label 5 in Figure 14) initiates
the sampling and readback of the number of measurements
defined in the Samples box.
• Clicking Continuous Capture (see label 5 in Figure 14)
performs a continuous capture from the ADC. Clicking
Continuous Capture a second time to stop sampling.
Window Tabs
There are five tabs available in the tabs area (labeled 3 in Figure 14)
of the main window: Configure, Waveform, Histogram, FFT, and
Summary. These tabs are used to switch among device
configuration, waveform analysis, histogram analysis, FFT
analysis, and a summary of the last capture. 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.
Graph Tools
Graph tools are provided within each tab to allow you to control
the cursor, zooming, and panning (see Figure 15) within the
graphs displayed.
