evaluation board. Channel B corresponds to Channel 2 on the
FIFO schematics and the top FIFO (U101) on the evaluation
board (closest to the Analog Devices logo). See the Jumpers

ADDITIONAL CONFIGURATION OPTIONS
Other options under the configuration pull-down menu include
Windowing, Power Supply, and Y-Axis.
Windowing
Choose either the Hanning or Blackman Harris (default)
windowing functions or turn windowing off. See the
Windowing Functions section for a description of Hanning and
Blackman Harris windowing. Click OK.
If you choose None, the Coherent Sampling Calculator window
opens (see Figure 4).
As a last step, choose File > Configuration File > Save
Configuration from the pull-down menu to save the
configuration for future use. Choose a file name and a
location to save the file.

For the calculator to work properly, the correct sampling
frequency must be entered under Config > FFT. Select either the
desired approximate Analog Input Frequency or the # of Sine
Wave Cycles. Enter the value in the dialog box (not labeled) and
click Calculate to view the Coherent Frequency. The Coherent
Frequency and Number of Integer Cycles will display in the
gray boxes. Click OK to exit the Coherent Sampling Calculator.
Power Supply
This option opens under Config > Power Supply, and users can
enter the value of the ADC analog and digital voltage supplies
(see Figure 5). Note this for user documentation only. No
external control is provided. ADC Analyzer displays this
information when data is captured. See the ADC Analyzer
Functions section for more information.
Y-Axis
Use the Y Axis screen to configure the display of the FFT
Y-Axis. Go to Config > YAxis to change the default value of –
130, which is a typical setting for the noise floor of a 14-bit
ADC with 16,384 samples in the FFT calculation.
