UG-1225

DESCRIPTION OF ANALYSIS WINDOW

Click Proceed to Analysis in the chip view to open the window,
as shown in Figure 15. The analysis view contains the
Waveform tab, Histogram tab, and FFT tab.

WAVEFORM TAB

The Waveform tab displays data in form of time vs. discrete
data values with the results, as shown in Figure 16. The
Capture pane contains capture settings, which reflect into the
registers automatically before data capture.
Capture
General Capture Settings
The Sample Count list allows the user to select the number of
samples per channel per capture.
The user can enter the input sample frequency in kSPS in the
Throughput(kSPS) box. Refer to the
determine the maximum sampling frequency for the selected
mode.
Device Configuration
The Mode list can be set between hardware mode, meaning
that the device is configured through digital input pins, or
software mode, which allows reading and writing the memory
map and enables a wider range of features. Refer to the
AD7606B data sheet to determine the benefits of each mode.
The Parallel/Serial Capture list allows the user to select the
data interface between parallel or serial.
The Oversampling Ratio list can be set between 2 and 64 (in
hardware mode) or 256 (in software mode) and provides
improved signal-to-noise ratio (SNR) performance. Refer to the
Figure 15. Analysis View

EVAL-AD7606BFMCZ
AD7606B data sheet to determine the maximum oversampling
ratio for the selected oversampling mode.
The Input Range, when hardware mode is enabled, allows
selection between ±10 V and ±5 V. In software mode, the input
span is selected either in the memory map or the pop-up menu
in chip view (see Figure 13).
The Toggle Reset Pin button allows the user to issue a full reset to
the AD7606B. Refer to the AD7606B
the different types of reset available on the device.
Run Once
Click Run Once to start a data capture of the samples at the
sample rate specified in the Throughput(KSPS) box for the
number of samples stated in Sample Count list. These samples
are stored on the FPGA device and are only transferred to the
PC when the sample frame is complete.
Run Continuously
Click Run Continuously to start a data capture that gathers
samples continuously with one batch of data at a time. The Run
Once operation is run continuously.
Results
Display Channels
Display Channels allows the user to select the channels to
capture. The channel data is shown only if that channel is
selected before the capture.
Waveform Results
Waveform Results displays amplitude, sample frequency, and
noise analysis data for the selected channels.
