EVALUATION BOARD SOFTWARE

LAUNCHING THE SOFTWARE

Follow these steps to launch the ACE software:
1. From the Start menu, select All Programs > Analog Devices
> ACE > ACE.exe to open the main window shown in
13.
2. The EV-ADAQ7768-1FMC1Z icon appears in the Attached
Hardware section.
3. If the EV-ADAQ7768-1FMC1Z is not connected to the USB
port through the SDP-H1 board when the software is
launched, the EV-ADAQ7768-1FMC1Z board icon does not
appear in the Attached Hardware section. Connect the EV-
ADAQ7768-1FMC1Z and SDP-H1 board to the USB port of
the PC and wait a few seconds. Then continue following these
instructions.
4. Double-click the EV-ADAQ7768-1FMC1Z board icon to open
the window shown in Figure
5. Click Software Defaults and then Apply Changes.
6. Click Proceed to Analysis to open the EV-
ADAQ7768-1FMC1Z analysis shown in

START-UP SEQUENCE

After running the software, the following events occur:
1. The software accesses the EEPROM on the main evaluation
board, which contains the board ID.
2. Once the EEPROM value is verified, the PC loads the corre-
sponding firmware to the FPGA on the SDP-H1.
3. After the loading of the firmware, the SDP-H1 supplies the 3.3
V to the main evaluation board and establishes communication
with the ADAQ7768-1.
4. The software then loads a preset of register values to the user
register map of the ADAQ7768-1 to configure it to the tool's
default operating mode.

DESCRIPTION OF THE ANALYSIS WINDOW

Click Proceed to Analysis in the chip view window to open the
window shown in Figure 15. The Analysis view window showcases
the performance of the EV-ADAQ7768-1FMC1Z. Before performing
any measurements, set the Capture Settings
The Analysis view window contains the Waveform
Histogram (Figure 18), and FFT tabs
Capture Settings
The General Capture Settings configures the sample count and
the output data rate (ODR). These settings reflect in the registers
automatically before data capture.
The Sample Count selects the number of samples per capture.
The default value is set at 8192 samples, which can also be
changed to the selection of the dropdown list, ranging from 512 to
131072 samples.

EVAL-ADAQ7768-1
The ODR (Output Data Rate) is automatically calculated by the
software based on the selected ADC filter settings. By default, this
is set to 256 kSPS.
Click Run Once in the Capture Settings section to start a data
capture of the samples at the sample rate specified in the Sample
Count dropdown list. These samples are stored on the FPGA
device and are only transferred to the PC when the sample frame is
complete.
Click Run Continuously in the Capture Settings section to start
a data capture that gathers samples continuously with one batch of
data at a time. This runs the Run Once operation continuously.
Analysis
The General Settings section sets up the preferred configuration of
the fast fourier transform (FFT) analysis. This configuration sets the
number of tones to analyze and the fundamental strategy to use.
The Windowing section sets up the preferred windowing type to
use in the FFT analysis. It also configures the other parameters
to include in the analysis (i.e., number of harmonics, fundamental
bins, harmonic bins, DC bins, and worst other bins).
The Single Tone Analysis and Two-Tone Analysis sections set
up the fundamental frequencies included in the FFT analysis. When
one frequency is analyzed, use the Single Tone Analysis section.
When two frequencies are analyzed, use the Two-Tone Analysis
section.
Results
Click Export to export the captured data. The waveform, histogram,
and FFT data are stored in .xml files along with the values of the
parameters at capture.
Waveform Tab
The Waveform tab displays data as time vs. discrete values with
the results, as shown in Figure
The data waveform graph shows each successive sample of the
µModule output. Zoom in on and pan over the waveform graph
using the embedded waveform tools above the graph.
Click the display unit's dropdown (shown with the Codes option
selected in Figure 17) to select if the data graph displays in units of
hexadecimal, volts, or codes. The axis controls are dynamic.
When selecting either the y-scale or x-scale dynamic, the corre-
sponding axis width automatically adjusts to show the entire range
of the µModule results after each batch of samples.
Histogram Tab
The Histogram tab contains the histogram graph, together with the
capture results related to the DC performance
