DESCRIPTION OF MAIN WINDOW
The following tools allow the user to control the operation of
the AD7606 evaluation board software and the capturing and
displaying of data from the ADC. When the software launches,
the main AD7606 evaluation software window opens (see
Figure 11).
The main evaluation software window, shown in Figure 11, has
the following features:
•
•
•
Menu bar
Control buttons
Configuration tab, Waveform tab, Histogram tab, FFT
tab, and Summary tab
Menu Bar
The menu bar, Label 1 in Figure 11, consists of the File and
Help menus.
•
•
•
•
The Oversample Mode drop-down menu (Label 4 in Figure 11)
enables and disables oversampling and chooses from rates of
oversample by 2, 4, 8, 16, 32, and 64. See the AD7606/AD7606-6/
AD7606-4, AD7607, AD7608, and AD7605-4 data sheets for more
information about the digital filter profile. The maximum output
data rate of the AD7606/AD7606-6/AD7606-4, AD7607, AD7608,
and AD7605-4 is limited by the selected oversampling rate.
Range
Save Data—This option saves captured data in comma
separated values (CSV) format for future analysis.
Load Data—This option loads previously captured data in
CSV format for analysis.
Print Front Panel—This option prints the front panel.
Save As Picture—This option saves the currently displayed
graph of data as an image in JPEG file format.
Exit—This option exits the program.
The 5V / 10 V Range drop-down menu (Label 5 in Figure 11)
selects the range to be used by the software, and alters the signal
analysis calculations for the Histogram, Waveform, and FFT
tabs. This drop-down menu does not change the actual range of
the ADC, which is determined by the state of the RANGE pin.
The range of the ADC is set by inserting either the R1 resistor
or R2 resistor to tie the RANGE pin to DGND or VDRIVE. The
evaluation board is supplied with R1 inserted which ties the
RANGE pin to VDRIVE and sets the ADC range to ±10 V.
Ensure the range selected in the 5V / 10 V Range drop-down
menu matches the hardware configuration set by the R1 and R2
resistors. Failing to select the correct range can lead to inaccurate
calculations of the graphs and results displayed on the Histogram,
Waveform, FFT, and Summary tabs.
The Help menu includes the following option:
•
Oversampling
Oversampling is not available on the AD7605-4.
The File menu includes the following options:

Taking Samples
If the Continuous button is clicked, the label on the button changes
to Stop, and the software repeats the capture of the selected
number of samples indefinitely until the user clicks Stop. While
the software is in the continuous capture mode, the data in the
Waveform, Histogram, FFT, or Summary tab is also continuously
updated.
To initiate a conversion and capture the sample data, click the
Sample button or the Continuous button. Both the Sample and
the Continuous buttons are located at the top of the window
(Label 8 in Figure 11).
When the Sample button is clicked, the software instructs the
EVAL-SDP-CB1Z board to take the required number of samples
at the required sampling rate from the evaluation board. Once
the required number of samples are captured, the capturing
process stops and the data displayed in the Waveform,
Histogram, FFT, or Summary tab updates.
No data appears on the screen if no active channels are selected.
See the Selecting Active Channels section for details on how to
select active channels.

WAVEFORM CAPTURE TAB
The Waveform tab, shown in Figure 13, is used for waveform
capture.
The waveform analysis reports the amplitudes recorded from
the captured signal as well as the fundamental frequency of the
signal tone. The analysis report is generated for the ADC
channel selected via the ADC 1 ON/ADC 1 OFF to ADC 8
ON/ADC 8 OFF buttons (Label 1 in Figure 13).
At the bottom right of the graph are the zoom options. These
allow the user to zoom in to look closer at a sample. The Waveform
Analysis section (Label 2 in Figure 13), which is located beneath
the waveform graph, contains information about the samples taken;
the peak-to-peak amplitude, the minimum/maximum amplitude,
the mean, the standard deviation of the captured data, and the
fundamental frequency of the signal tone are shown.
The waveform graph displays the information for all eight input
channels or as many channels as desired. Eight buttons located
to the right of the graph, labeled ADC 1 ON/ADC 1 OFF to
ADC 8 ON/ADC 8 OFF, selects which channel data displays
(Label 1 in Figure 13). An indicator, located to the right of the
graph (Label 3 in Figure 13), shows what color graph represents
each channel when the data from several channels is displayed.
Data Capture Display
Four tabs display the conversion data in different formats:
Waveform, Histogram, FFT, and Summary.
The tools shown in Figure 12 allow user control of the different
chart displays within the four tabs.

HISTOGRAM TAB
13283-015
Figure 14 shows the Histogram tab. To perform a histogram
test, select the Histogram tab in the AD7606 Evaluation
Software main window and click the Sample button or
Continuous button. A histogram requires a quality signal
source applied to at least one of the inputs (V1 to V8).
The Histogram tab displays a histogram of the captured ADC
codes. It can give an indication of the performance
of the ADC in response to dc inputs. The Histogram Analysis
section contains information about the samples taken, for
example, the maximum and minimum codes captured.

AC TESTING—FFT CAPTURE
The user can choose to display the information for one, several,
or all eight channels in the FFT tab using the ADC 1 ON/ADC
1 OFF to ADC 8 ON/ADC 8 OFF buttons.
13283-016
Figure 15 shows the FFT tab. The FFT tab analyzes the
performance of an ADC in the frequency domain. The FFT tab
tests the traditional ac characteristics of the converter and displays
a fast Fourier transform (FFT) of the results. The FFT tab shows
a plot of the computed FFT data.
The Spectrum Analysis pane contains further information
about the analysis, such as the calculated values of signal-tonoise ratio (SNR), signal-to-noise-and-distortion (SINAD), and
total harmonic distortion (THD) (see Figure 15).

well as some of the key performance parameters, such as SNR,
THD, S/N +D, and Dynamic Range (see Label 1 in Figure 16).
Figure 16 shows the Summary tab. This tab captures and
