provide 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 15) 

indicates whether the 

EVAL-AD7403FMCZ

 board has 

been detected.

 

 

The

 FPGA Settings

 section (labeled 6 in Figure 15) 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 15) 

allows selecting the number of samples to be captured in a 
single acquisition.

 

 

Clicking

 Single Capture

 (see label 5 in Figure 15) initiates 

the sampling and readback of the number of measurements 
defined in the 

Samples

 box.  

 

Clicking

 Continuous Capture

 (see label 5 in Figure 15) 

performs a continuous capture from the ADC. Clicking 

Continuous Capture

 a second time stops sampling.  

Window Tabs 

There are five tabs available in the tabs area (labeled 3 in Figure 15) 
of the main window: 

Configure

Waveform

Histogram

FFT

, and 

Summary

. These tabs are used to switch among device configu-

ration, 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 16) within the 
graphs displayed.
