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
•

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.
